Answer 1

Answer:

Step-by-step explanation:

Find the attachment

1-sin theta/ costheta

Is same as sec theta-tan theta

So, do conjucate multiplication.

√(1- sintheta )(1-sintheta)

-------------------------------------

√(1+sintheta)(1-sintheta)

Now 1-sinsquare they = Cossquare theta

So u get..

√(1- sintheta )^2

= ----------------------

√(1-sintheta^2)

(1- sintheta )

= ------------------

Costheta
