Answer: 1-sintheta costheta

Step-by-step explanation: cos cube theta+sin cube theta/ cos theta + son theta

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

because-- (a cube + b cube )= ( a+b)(a sq.- ab + b sq.)

= sin sq. - sin theta cos theta + cos sq. theta

= 1- sin theta cos theta [ ANS]

becuuse-- (sin sq. theta + cos sq. theta)= 1
