tan(x)^2-sin(x)^2 all over tan(x)^2=sin(x)^2

i need mad
you need to get one side to look like the other
one rule: you cant touch the side you are trying to get it to look like

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tanx =

• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Consider the left side

= -

= 1 - cos²x

= sin²x = right side ⇒ verified

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
