An equation of the tangent line to the curve

What does it mean by input the answer in the form of ax+m? I have the answer in terms of pi as req

thx

An equation of the tangent line to the curve y =x) =x(3 cosx 11 sinx) at mm = :- Hote: Please follow these instructions carefully: (a) Expressdw) andf(4w) in terms of w. Simplify those expressions by evaluating the exact values of sin[41r) and coach}. (b) Your answer should be in the form ax+m. when calculating a and m, approximate 1r by 3.14
