Question

what is sin theta + cos theta​

Answer 1

Answer:

sec(theta) = 1 / cos(theta) = c / b. tan(theta) = sin(theta) / cos(theta) = a / b. cot(theta) = 1/ tan(theta) = b / a. sin(-x) = -sin(x) csc(-x) = -csc(x)

Answer 2

Answer: a]sin2θ + cos2θ   =   1.

b) 1 + tan2θ   =   sec2θ

c) 1 + cot2θ   =   csc 2θ

a') sin2θ   =   1 − cos2θ.

 cos2θ   =   1 − sin2θ.

Step-by-step explanation:

sin θ  =      1  

csc θ         csc θ  =      1  

sin θ

cos θ  =      1  

sec θ         sec θ  =      1  

cos θ

tan θ  =      1  

cot θ         cot θ  =      1  

tan θ
