Evaluate the limit of (tanx)^2/(1-cosx) as x tends to 0
Please show your work. Thanks!
Rewrite the limand as
[tex]\dfrac{\tan^2(x)}{1 - \cos(x)} = \dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))}[/tex]
Multiply the numerator and denominator by 1 + cos(x). Then
[tex]\dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))} \cdot \dfrac{1+\cos(x)}{1+\cos(x)} = \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)(1 - \cos^2(x))} \\\\= \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)\sin^2(x)} \\\\ = \dfrac{1 + \cos(x)}{\cos^2(x)}[/tex]
As x goes to 0, the limand goes to (1 + 1)/1² = 2.
We are given with a limit :-
[tex]{\quad \blacktriangleright \blacktriangleright \blacktriangleright {\displaystyle \sf \lim_{x\to 0}\dfrac{\tan^{2}(x)}{1-\cos (x)}}}[/tex]
We know that ;
[tex]{\boxed{\bf \dfrac{\sin (\theta)}{\cos (\theta)}=\tan (\theta)}}[/tex]Using this , the above limit can be written as ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)}{\cos^{2}(x)\{1-\cos (x)\}}}[/tex]
Multiplying and dividing both numerator and denominator by [tex]{\sf 1+\cos (x)}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos (x)\}\{1+\cos (x)\}}}[/tex]
We knows a identity that is
[tex]{\boxed{\bf a^{2}-b^{2}=(a+b)(a-b)}}[/tex]Using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos^{2}(x)\}}}[/tex]
We knows another Trigonometric identity i.e ;
[tex]{\boxed{\bf 1-\cos^{2}(\theta)=\sin^{2}(\theta)}}[/tex]Now , using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\cancel{\sin^{2}(x)}\{1+\cos (x)\}}{\cos^{2}(x)\cancel{\sin^{2}(x)}}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{1+\cos (x)}{\cos^{2}(x)}}[/tex]
Putting the limit we have ;
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+\cos (0)}{\cos^{2}(0)}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+1}{1^{2}} \quad \qquad \{\because \cos (0)=1\}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{2}{1}}[/tex]
[tex]{:\implies \quad {\displaystyle \therefore \quad \bf \underline{\underline{\lim_{x\to 0}\dfrac{\tan^{2}(x)}{1-\cos (x)}=2}}}}[/tex]
2 trig ratios missing sides and angels
Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos66° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{13}{x}[/tex] ( multiply both sides by x )
x × cos66° = 13 ( divide both sides by cos66° )
x = [tex]\frac{13}{cos66}[/tex] ≈ 32.0 ( to the nearest tenth )
Multiply.

PLZ PLZ PZLZ HELP BRAINYLEST FOR THE BEST
Answer:
w = 63
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 interior angles.
w + 28 is an exterior angle of the triangle , then
w - 2 + w - 33 = w + 28 , that is
2w - 35 = w + 28 ( subtract w from both sides )
w - 35 = 28 ( add 35 to both sides )
w = 63
PLZ help is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement.
If no, justify your answer.
Answer:
Yes
Step-by-step explanation:
These triangles are congruent by one of two theorems. The first one would be HL, or hypotenuse leg, or side, angle,side. the congruence statement would be
Angle Y is congruent to angle B
Side YZ is equal to BC
Side YX is equal to Side BA
So, triangle XYZ is congruent to triangle ABC by either the HL, OR THE SAS theorem.

(x-1)(x+7)=(x+1)(x-3)
Answer:
x = 1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form: x= 1/2
Decimal form: x = 0.5
Answer:
x= 1/2
Step-by-step explanation:
Let's solve your equation step-by-step.
(x−1)(x+7)=(x+1)(x−3)
Step 1: Simplify both sides of the equation.
x2+6x−7=x2−2x−3
Step 2: Subtract x^2 from both sides.
x2+6x−7−x2=x2−2x−3−x2
6x−7=−2x−3
Step 3: Add 2x to both sides.
6x−7+2x=−2x−3+2x
8x−7=−3
Step 4: Add 7 to both sides.
8x−7+7=−3+7
8x=4
Step 5: Divide both sides by 8.
8x/8 = 4/8
x = 1/2
A 14.5-gallon gasoline tank is $\frac{3}{4}$
full. How many gallons will it take to fill the tank? Write your answer as a mixed number.
The number of gallons it take to fill the tank is 3.625 gallon.
Given that, a 14.5-gallon gasoline tank is 3/4 full.
Let the number of gallons it take to fill the tank is x.
Now, the number of gallons of gasoline tank = 14.5×3/4
= 14.5×0.75
= 10.875
Here, 10.875+x=14.5
x=14.5-10.875
x=3.625
Therefore, the number of gallons it take to fill the tank is 3.625 gallon.

Billy dove off a cliff into the water. The cliff was 15 ft. above sea level. After diving into the water, he swam 5 ft. below the opposite elevation of the cliff and found a golden ring. At what elevation did he find the golden ring?
Answer:
Billy found the ring at -20 ft
Step-by-step explanation:
He started at 15 ft
He dove off the cliff, then swam 5 feet under the opposite of the cliff's elevation
The opposite of the cliff's elevation would be -15, and if he swam five feet under that, it would be -15 + -5 = -20
So, Billy found the ring at -20 ft

BRAINLIEST 3/5(x−710)=−314
Answer: x = 560/3
Step-by-step explanation:
First! We are going to be using the PEMDAS method! If you have any questions about this method please go ahead and ask below! The first step in our equation is the P - parenthesis, so we are going to multiply [tex]\frac{3}{5}[/tex] to everything inside of the parenthesis (x and -710)!
[tex]\frac{3}{5} (x -710) = -314[/tex]
[tex]\frac{3}{5}x+(\frac{3}{5}*-710)=-314[/tex]
[tex]\frac{3}{5}x -426 = -314[/tex]
Now, we are going to add 426 to both sides of the equation, to single out the "x" variable!
[tex]\frac{3}{5}x= 112[/tex]
Finally, let's multiply both sides by [tex]\frac{5}{3}[/tex] to cancel out the [tex]\frac{3}{5}[/tex] fractions, to get the "x" variable alone.
[tex]x=\frac{560}{3}[/tex]

Which of the following is an equation of the line through (2, 3) and (−1, −12
Answer:
y = 5x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 3 ) and (x₂, y₂ ) = (- 1, - 12 )
m = [tex]\frac{-12-3}{-1-2}[/tex] = [tex]\frac{-15}{-3}[/tex] = 5 , then
y = 5x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 3 )
3 = 10 + c ⇒ c = 3 - 10 = - 7
y = 5x - 7 ← equation of line
