Use the rule for differentiating a constant multiple and the rule for differentiating a difference of two functions. Answer \(f′(x)=2\sec^2 x+3\csc^2 x\) WebWhat is the definition of derivative? To find f ′ ( 0), you need to calculate the limit of sin h 2 − sin 0 2 h as h → 0. But if you use h → 0 +, you will end up with a different answer than if you went with h → 0 −. For the actual calculation, you should know that lim h → 0 sin h 2 h 2 = 1, so lim h → 0 sin h 2 h = lim h → 0 ... dhss full form
