Question

Trig help!

Answer 1

sec(theta) = 9
Use identities to find the exact values of
cos(theta)
csc(theta - pi/2)
tan^2(theta)

Answer 2

cos theta = 1/sec theta = 1/9

Answer 3

oh yeah. you just flip them. thanks!

Answer 4

cosec theta = 1/sin theta

Answer 5

cosec (theta -pi/2) = 1 / -sin(pi/2 - theta)

Answer 6

cosec (theta - pi/2) = - sec theta

Answer 7

tan^2 theta+ sec^2 theta = 1
tan^2theta = 1- sec^2 theta

Answer 8

now u just have to feed in the values and solve

Answer 9

Thanks!
