WebTo find the derivative of function in the form y = x f ( x), you need to know that ( ln f ( x)) ′ = f ′ ( x) f ( x), so f ′ ( x) = f ( x) ( ln f ( x)) ′. Then differentiate both sides and think that y = f ( x) and x is the independent variable, i.e. ( x y) ′ + ( y x) ′ = 0. st mary\u0027s/st peter\u0027s church rome nyWebif y varies directly as x, and y=9 when x=4, find y when x=16. When you see "direct variation" think: y = kx. To find k, use "y=9 when x=4": y = kx 9 = k(4) 9/4 = k. so, our equation is: y = (9/4)x. now, we can answer: find y when x=16 y … st marychurch and babbacombe con clubWebConsider the following. x = 5 − 2t, y = 2 + 5t Eliminate the parameter and write the resulting rectangular equation whose graph represents the curve.
