Find the acute angle theta, if : 3 cosec^(2)theta - 2 sec theta = 0.

Find the acute angle theta if 4sin^(2) theta=3 .

Write the acute angle theta satisfying sqrt(3)sin theta=cos theta

If theta is an acute angle such that 2 sin^(2)theta - 2sqrt2 * sin theta +1 =0,"then" : theta= A) 30^(@) B) 45^(@) C) 60^(@) D) 90^(@)

Find the acute angle theta satisfying the equation 2sin^(2)theta-2sqrt2sintheta+1=0.

Find an acute angle theta when (cos theta-sin theta)/(cos theta+sin theta)=(1-sqrt(3))/(1+sqrt(3))

If sin theta =(3)/(5) and theta is acute, then find the value of (tan theta - 2 cos theta )/(3sin theta+sec theta ) .

If theta is an acute angle such that 4sin^(2) theta-2(sqrt3+1)sintheta+sqrt3=0,"then": theta= A) 30^(@) or 60^(@) B) 45^(@) or 90^(@) C) 0^(@) or 180^(@) D)none of these

If sintheta = sqrt3 costheta, 0^circ lt theta lt 90^circ , then the value of 2sin^(2)theta + sec^(2)theta + sin theta sec theta + cosec theta is: यदि sintheta = sqrt3 costheta, 0^circ lt theta lt 90^circ , , तो 2sin^(2)theta + sec^(2)theta + sin theta sec theta + cosec theta का मान है:

If sec theta+tan theta= 2+sqrt5 and theta is an acute angle, then the value of sin theta is: यदि sec theta+tan theta= 2+sqrt5 तो sin theta का मान क्या होगा जहाँ theta न्यून कोण है
