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

it is true

step-by-step explanation:

all the combinations add up i used   calculator

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

i suppose it should be (y=2x-5)
