(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Partial derivative of R = vt cos x with respect to t

2. Relevant equations

NA

3. The attempt at a solution

Keeping the other variables constant, I get 'v cos x'. (t is 1)

I just want to check this, because it's part of a larger problem and I feel my answer is way off because of this function. I'm a bit rusty on my calculus, it's been ... 13 years since I did it in highschool!

Also, if I calculate the partial derivative with respect to x, I get '-vt sin x'?
