int(sin12 theta-sin9 theta)/(2cos7 theta-1)*d theta" is equal to" (1) (cos2 theta)/(2)+(cos5 theta)/(5)+c ( 2) (cos5 theta)/(2)-(cos2 theta)/(5)+c (3) (cos2 theta)/(5)-(cos5 theta)/(2)+c (4) (cos2 theta)/(2)-(cos5 theta)/(5)+c

If sin theta=(3)/(5), evaluate (cos theta-(1)/(tan theta))/(2cot theta)

The numerical value of 9/(1+cot^2theta)+4cos^2theta+5/(1+tan^2theta)

If cot theta=(1)/(sqrt(3)), show that (1-cos^(2)theta)/(2-sin^(2)theta)=(3)/(5)

If p cos c theta+q cot theta=2 and p^(2)cos ec^(2)theta-q^(2)cot^(2)theta=5 then the value of sqrt(81p^(-2)-q^(-2)) is

If "cosec" theta + cot theta = (13)/5 then cot^(2) theta - "cosec"^(2) theta = (25)/12
