Someone Plz Help Me!! IDK How To Do This Prove each Trigonometric Identity
1. cot x sec⁴x = cot x +2 tan x + tan³x
2. (sin x)(tan x cos x - cot x cos x)= 1 - 2 cos²x
3. 1 + sec²x sin²x=sec²x
4. sin x/1 - cos x + sin x/ 1 + cos x = 2 csc x
5. - tan²x + sec²x = 1

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

yes

step-by-step explanation:

yes

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
