(1 point) Suppose w =6x2+4y, x = 7 cos(t) + 5 sin(t) , and y = 7 cos(t) - 5 sin(t) . Compute dwldt in two different ways: Find Ow/ox and Ow/dy as functions of t. dw/ox = 12(7cos(t)+5sin(t)) awldy = 8(7 cos(t)-5sin(t)) Now use your answers above to find dw/dt using the chain rule. dwldt = 12(7 cos(t)+5sin(t))(-7cos Write w as a function of t. WE Now use your answer above to find dw/dt directly. dwldt = Use your answers above to find dw/dt att = n. dw dt It=n =
