If ` (cos^(3) theta )/( (1- sin theta ))+( sin^(3) theta )/( (1+ cos theta ))=1+ cos theta `, then number of possible values of ` theta ` is ( where ` theta in [0,2pi]`)

Text Solution

Verified by Experts

The correct Answer is:
`theta = (pi)/(2)` which is not possible.

(sin theta)/(1-cos theta)=(1+cos theta)/(sin theta)

If the system of linear equations {:((cos theta)x + (sin theta) y + cos theta=0),((sin theta)x+(cos theta)y + sin theta=0),((cos theta)x + (sin theta)y -cos theta=0):} is consistent , then the number of possible values of theta, theta in [0,2pi] is :

(cos theta)/(1-sin theta)=(1+cos theta+sin theta)/(1+cos theta-sin theta)

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

(1 + sin theta-cos theta) / (1 + sin theta + cos theta)

(1 + cos theta + sin theta) / (1 + cos theta-sin theta) = (1 + sin theta) / (cos theta)

cos theta/(1+sin theta)=(1-sin theta)/cos theta

(1 + sin theta-cos theta) / (1 + sin theta + cos theta) =

(sin ^ (3) theta + sin3 theta) / (sin theta) + (cos ^ (3) theta-cos3 theta) / (cos theta) =

(1+cos theta+sin theta)/(1+cos theta-sin theta)=(1+sin theta)/(cos theta)
