Hi can anyone help me in ths question. I dnt know what to do in the second part.
Question is : the parametric equation of a curve are x=2cost , y=5+3cos2t , where 0<t<pie .
Express dy by dx in terms of t, and hence show that the gradient at any point of the curve is less than 6.
now use values of t like o pi/2 and pi to get different ans of dy/dx. u will get values less then 6 hope this image is clear
