Question

Match the following identities and formulas:
76. sin^2 theta + cos^2 theta=
77. tan^2 theta + 1=
78. cot^2 theta + 1=
79. (sin theta)/(cos theta)=
80. (cos theta)/(sin theta)=

a. csc^2 theta
b. tan theta
c. 1
d. cot theta
e. sec ^2 theta

Answer 1

i know 76 is C

Answer 2

these mainly take time and use to memorize. you can figure these out but im no good at it.
76 = c. 77 = e. 78 = a. 79 = b. 80 = d
