Question

Julia wants to simplify the term sec^2 theta-1/cot^2 theta+1 in a trigonometric identity that she is proving. Which of the following identities should use to help her? Select all that apply. (2 ANSWERS)
a. sin^2 theta+cos^2 theta=1
b. sec^2 theta-tan^2 theta=1
c. sec theta=1/cos theta
d. cot theta=1/tan theta
e. 1=csc^2 theta-cot^2 theta

Answer 1

d&e would be my first choices

Answer 2

Is it c&e? cuz that's what I think it is

Answer 3

w e l l Which is it?

Answer 4

sec^2 theta - tan^2 theta = 1
1=csc^2 theta - cot^2 theta
B & E would be your answers. Thank me later 2023 :)

Answer 5

hey guys
