d/dt cot (t) dt = - cosec2(t)
y=x3+ 2x, dx/dt=5, x=2, dy/dt=? Differentiate the equation with respect to t. dy/dt=3x2*dx/dt Substitute in known values. dy/dt=3(2)2 * (5) dy/dt=60
dx/dt= 25 dy/dt=60 dz/dt=? x^ 2+y^2=z^2 2 x dx/dt +2 y dy/dt = 2 z dz/dt @ t = 2 x= 2* 25 = 50 y= 2* 60 =120 z=SQR (50^2 +120^2) = 130 2*50*25 +2* 120* 60 = 2* 130* dz/dt dz/dt = 65 mph .
