Question

Help please! sin(90-theta)csc theta / cot theta =1

Answer 1

Use trig identities to transform the left side to the right. Here's the equation in better form...\[\frac{ \sin(90-\theta)\csc \theta }{ \cot \theta }=1 \]

Answer 2

sin(90 - theta) = sin(90)cos(90) + cos(theta)sin(theta)
= cos(theta)sin(theta)

Answer 3

I meant a minus sign not plus.

-cos(theta)sin(theta)

Answer 4

\[\frac{ (\cos(\Theta)\sin(90)(\sin(\Theta) }{ \cos(\Theta)\sin(\theta) }\]

Answer 5

simplify.

Answer 6

So... (cos(theta)(sin(theta)/(cos(theta)(sin(theta) and then it all equals 1?

Answer 7

Yes

Answer 8

Thanks! :D
