**Calculus**

Those are the answers I got that I thought were wrong, but the online assignment wanted the value of f(9)=-479 and f(-1)=21, not 9 and -1. Thank you!

**Calculus**

Find the local maximum and local minimum of the function. f(x) = x^3 − 12x^2 − 27x + 7
*November 9, 2015*

**Calculus-antiderivative**

Find f. f ''(θ) = sin θ + cos θ, f(0) = 5, f '(0) = 3 My steps: f'(θ)=cosθ-sinθ+C When f'(0)=3, C=-2, so f'(θ)=cosθ-sinθ-2. f(θ)=-sinθ-cosθ-2x+D When f(0)=5, D=6, so f is -sinθ-cosθ-...
*November 9, 2015*

**Calculus**

Find the critical numbers of the function. (Use n to denote any arbitrary integer values.) f(θ) = 12 cos θ + 6 sin2θ My answer was pi/2 and 3pi/2, but those were wrong. I don't understand the 'n' part, either.
*November 9, 2015*

**Calculus**

Find the absolute maximum and absolute minimum values of f on the given interval. f(x) = 17 + 4x − x^2, [0, 5] I got -13 and 17, but the answers were wrong. Take the derivative for the critical values, right? To get 2 as a critical value. What from there?
