" सिद्ध करें कि "theta=(pi)/(3)" पर "sin theta(1+cos theta)" महत्तम है। "

2 cos (theta - pi //2) + 3 sin (theta + pi//2) - (3sin theta + 2 cos theta ) = ? A. cos theta - sin theta B. sin theta - cos theta C. sin theta + cos theta D. cot theta - tan theta .

If tan theta =3/5, 0^@ prec theta prec 90^@ then sin theta cos theta is equal to : यदि tan theta =3/5 है और 0^@ prec theta prec 90^@ है, तो sin theta cos theta का मान ज्ञात करें |

Find the value मान ज्ञात करें : (sin theta+cos theta-1)/(sin theta-cos theta+1)xx(tan^2 theta (cosec^2 theta -1))/(sec theta -tan theta )

If (cos^(3) theta )/( (1- sin theta ))+( sin^(3) theta )/( (1+ cos theta ))=1+ cos theta , then number of possible values of theta is ( where theta in [0,2pi] )

If (cos^(3) theta )/( (1- sin theta ))+( sin^(3) theta )/( (1+ cos theta ))=1+ cos theta , then number of possible values of theta is ( where theta in [0,2pi] )

If (cos^(3) theta )/( (1- sin theta ))+( sin^(3) theta )/( (1+ cos theta ))=1+ cos theta , then number of possible values of theta is ( where theta in [0,2pi] )

If (cos^(3) theta )/( (1- sin theta ))+( sin^(3) theta )/( (1+ cos theta ))=1+ cos theta , then number of possible values of theta is ( where theta in [0,2pi] )

If cosec theta =13/12 , then the value of (2 sin theta -3cos theta )/(4sin theta -9 cos theta ) is: यदि cosec theta = 13/12 , तो (2 sin theta -3cos theta )/(4sin theta -9 cos theta ) का मान ज्ञात करें

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