जर `sin theta = 4/5` तर `cos theta` काढा.

(5) If sin theta = 4/5 and cos theta =3/5, then tan theta =

Find tan theta if sin theta = 4/5 and 5 times cos theat = 3.

If theta is in 1st quadrant, sin theta=3/5 , then cos theta =? .

Use De Moveres Theorom and simplify . (( cos 5 theta + i sin 5 theta ) ^(2))/( ( cos 4 theta -i sin 4 theta ) ^(3))

If theta lies in the first quadrant and 5 tan theta = 4 , " then " (5 sin theta - 3 cos theta )/( sin theta + 2 cos theta )= .............. A) 0 B) 1 C) 1/6 D) 5/14

If 3 sin theta + 4 cos theta=5 , then find the value of 4 sin theta-3 cos theta . A) 0 B) -5 C) 5 D) 4

Prove that : (1-sin theta cos theta)/ (cos theta (sec theta - cosec theta)) times (sin^2 theta - cos^2 theta)/(sin^3 theta + cos^3 theta) = sin theta

If tan theta = (4)/(3) , then 3sin theta - 4 cos theta =

(xv) (cos^2 theta) / (1- tan theta) +( sin^3 theta)/ (sin theta - cos theta) = 1 + sin theta cos theta

If cos theta + sin theta = sqrt2 cos theta " then" cos theta - sin theta is equal to
