The range of `8 cos theta - 15 sin theta ` is

If theta in R - {(4n + 1) pi/4 , n in I} , then range of (cos 3 theta + sin 3 theta)/(cos theta - sin theta) is :

If theta in R - {(4n + 1) pi/4 , n in I} , then range of (cos 3 theta + sin 3 theta)/(cos theta - sin theta) is :

Find range of 'theta' if cos theta + sin theta is positive

Find the maximum and minimum values of : 15 cos theta-8 sin theta .

If sin theta = ( 8)/(17), then the value of cos theta and tan theta is (a) (15)/(17), (8)/(15) (b) (15)/(8) , (8)/(15) (c) (15)/(17), (15)/(8) (d) None of these

(1+ sin theta - cos theta )/( 1+ sin theta + cos theta ) + (1+ sin theta + cos theta )/( 1+ sin theta - cos theta ) =
