*Note that f /(x) denotes the derivative (the slope of the tangent) at (x,f(x)) Using . OR ie. at x = 4; Rules for Obtaining Derivative Functions. 1. Constant Rule If y = c then. 2. Power Rule If y = axn then . Proof of Constant Rule If y = c then. let f(x) = c. Proof of the Power Rule If y = axn then

of a given 1st-order differential equation on some open interval is a function that has a derivative and satisfies this equation for all x in that interval; that is, the equation becomes an identity if we replace the unknown function y by h and y’ by h’. (a) General solution: contains arbitrary constants, e.g., = g ( h(t) = g t2 + c1 t + c2

MATH 31
Find the first derivative of this function and say where it is defined and where it is not defined. (2) Express the function f(x)=sinx+cosx in the form f(x)=Asin(x+α), find A and α and plot the graph of this function. Similarly express the function g(x)=sinx−cosx in the form g(x)=Bsin(x+β) where −π/2
