A value of theta satisfying 4cos^(2)theta sin theta-2sin^(2)theta=3sin theta is

Solve: 4 cos ^(2) theta = 3 . (theta ^(@) le theta lt 360 ^(@)).

lim_(theta rarr(pi)/(6))(4cos^(2)theta-3)/(2sin theta-1)

If 4cos^2 theta-3 sin^2 theta+2=0 , then the value of tan theta is (where 0le theta यदि 4cos^2 theta-3 sin^2 theta+2=0 ,है, तो tan theta का मान क्या होगा ? (जहाँ 0le theta<90^@ )

Given : 4 sin theta = 3 cos theta , find the value of : (i) sin theta (ii) cos theta (iii) cot^(2) theta - "cosec"^(2) theta (iv) 4 cos^(2) theta - 3 sin^(2) theta + 2

If costheta=(8)/(17) ,verify that (3-4sin^(2)theta)/(4cos^(2)theta-3)=(3-tan^(2)theta)/(1-3tan^(2)theta) .

If costheta=(8)/(17) ,verify that (3-4sin^(2)theta)/(4cos^(2)theta-3)=(3-tan^(2)theta)/(1-3tan^(2)theta) .

If 3cos theta+4cos theta=5 then 4sin theta-3cos theta is equal to

Given : 4 sintheta = 3 cos theta , find the value of: 4 cos^2theta-3sin^2 theta +2
