For what values of `theta`,|sin θ|`=`|cos θ|`is possible?

The value of sin(90^@-theta) is

Find -the least value of sec^2theta+cos^2theta

Is sin theta=1 = cos theta possible? Give reasons

Choose the correct option The value of sin theta cos (90- theta)+cos theta sin (90- theta) is

Find the values of :a. sin60^@ cos30^@+cos60^@sin30^@

Show that (a+b) ^2=4ab cos^2theta is possible if a=b

The value of sin40^@-cos50^@ is

The value of cos(40^@+theta)-sin(50^@-theta) is

Verify the following identities by substituting the values of the trigonometric ratios with respect to the given values of theta .(i) sin^2theta+cos^2theta=1(theta=60^@)

Solve 2cos^2 theta+3 sin theta=0
