As `theta` increases from `0^(@)` to `90^(@)`, the value of `cos theta` : -

As theta increases from 0^(@) to 90^(@) , the value of sin theta : -

Find value of cos(90+theta)

If cos theta + sec theta = 2 ( 0^@ letheta le 90^@) , then the value of cos 10 theta + sec 11 theta is

If sqrt(3) sin theta - cos theta = 0 and 0^(@) lt theta lt 90^(@) , find the value of theta .

If tan^(2)theta - 3sectheta + 3=0, 0^(@) lt theta lt 90^(@) , then the value of sintheta + cos theta is:

If (cos^(2) theta)/(cot^(2) theta - cos^(2) theta) = 3 and 0^(@) lt theta lt 90^(@) , then the value of theta is

If sintheta - cos theta = 7/13 and 0 lt theta lt 90^(@) ,then the value of sin theta + cos theta is:

If 2 cos ^(2) theta + sin theta - 2=0 and 0^(@) le theta le 90 ^(@) find the value of theta.

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

If 2cos theta - sin theta = 1/sqrt(2), (0^(@) lt theta lt 90^(@)) then the value of 2sin theta + cos theta is:
