If the mapping `f(x) = ax + b, a < 0` maps `[-1, 1]` onto `[0,2]` then for all values of `theta`, `A=cos^2theta+sin^4theta` is :

If the mapping f(x)=ax+b,a lt0 and maps [-1, 1] onto [0, 2] , then for all values of theta, A=cos^(2) theta + sin^(4) theta is such that

If (sin 3theta)/(cos 2theta)lt 0 , then theta lies in

The sum of all values of theta in (0 , pi) satisfying sin^(2) 2 theta + cos^(4) 2 theta = 1 is:

If 5 sin theta - 4 cos theta = 0, 0^(@) lt theta lt 90^(@) , then the value of (5sintheta-2costheta)/(sintheta+3costheta) is :

If (1/(1+cosec theta ) - 1/(1-cosec theta ))cos theta= 2 , 0^circ lt theta lt 90^circ , then the value of sin^(2) theta + cot^(2) theta + sec^(2) theta is: यदि (1/(1+cosec theta ) - 1/(1-cosec theta ))cos theta= 2 , 0^circ lt theta lt 90^circ , है,तो sin^(2) theta + cot^(2) theta + sec^(2) theta का मान हैः

If sin^(8)theta+cos^(8)theta-1=0 then what is the value of cos^(2)theta sin^(2)theta

If cos theta + cos^2 theta = 1, then value of sin^2 theta + sin^4 theta is (a) -1 (c) 0 (c) 1 (d) 2

find all values of theta varepsilon[0,2 pi] for which 1)sin theta+cos theta=02)cos^(2)theta=1+sin theta
