`(tan t + cos t)/sin t`

If x = a (cos t + t sin t), y = a (sin t - t cos t), then at t = pi//4,(dy)/(dx)

If x=a(sin t-t cos t),y=a sin t then find the value of (d^(2)y)/(dx^(2))

If s=e^(t) (sin t - cos t) is the equation of motion of a moving particle, then acceleration at time t is given by

The angle made by any tangent to the curve x=a(t+sin t cos t),y=(1+sin t)^(2) with x- axis is:

7. x=a(cos t+t sin t),y=a(sin t-t cos t) find dy/dx
