If `2sin^(2)_(theta)-3sinta_(theta)+1=0` `theta` being positive angle, then the value of `theta` are

If 2(cos^(2)theta-sin^(2)theta)=1,theta is a positive acute angle , then the value of theta is

If sec theta-cos theta = 3/2 where theta is a positive acute angle. then the value of sec theta is:

2(cos^(2)theta-sin^(2)theta)=1(theta is a positive acute angle),then cot theta is equal to

If 2 sin 3 theta = 1 , then the value of theta is :

If 7 sin^2 theta +3 cos^2 theta = 4, and theta is a positive acute angle, then tan theta is equal to

If cos^(2)theta+2sin^(2)theta+3cos^(2)theta+4sin^(2)theta+......20terms=10025 and theta is an acute angle then the value of sin theta-cos theta is

If cos2 theta=sin4 theta, where 2 theta and 4 theta are acute angles,find the value of theta.

If sin^(2)theta_(1)+sin^(2)theta_(2)+sin^(2)theta_(3)+sin^(2)theta_(4)=0 then which of the following cannot be the value of cos theta_(1)+cos theta_(2)+cos theta_(3)+cos theta_(4)

If 2 sin^2 theta+3 sin theta-2=0 , 0^@ prec theta prec 90^@ then the value of theta is: यदि 2 sin^2 theta+3 sin theta-2=0 और 0^@ prec theta prec 90^@ है, तो theta बराबर है :
