If ` cos theta =4/5` and the angle `theta` is the second quadrant then `tantheta` is :

If sin theta=3/5 and the angle theta in the second quadrant, then find cottheta .

If cot theta=-(3)/(4) and theta is not in the second quadrant then 5sin theta+10cos theta+9sec theta+16cos ec theta-4cot theta=

If cot theta=-3//4 and theta is not in the second quadrant , then 5 sin theta + 10 cos theta + 9 sec theta + 16 " cosec" theta - 4 cot theta =

If tantheta=3 and theta lies in third quadrant then sintheta=

If tantheta=3 and theta lies in third quadrant then sintheta=

If cos theta =(3)/5 and theta is not in the first quadrant , then (5 tan(pi+ theta ) + 4 cos (pi-theta ))/( 5 sec ( 2pi- theta ) - 4 cot (2pi+ theta ))=

If sin theta = (2t)/(1+t^(2)) and theta lies in the second quadrant, then cos theta is equal to

If sintheta=3/5 and theta is in the second quadrant,find : cos(theta/2)

If sin theta sec theta = -1 and theta lies in the second quadrant, find sin theta and sec theta .
