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

Find the length of subtangent subnormal at a pont t on the curve x=a(cos t+ t sin t) y=a( sin t-t cos t)

Show that the normals to the curve x=a(cos t+t sin t);y=a(sin t-t cos t) are tangentl lines to the circle x^(2)+y^(2)=a^(2)

If x= a(cos t + tsin t), y= a(sin t- t cos t) , then dy/dx .............. A) cot t B) -tan t C) sqrt (tan t) D) tan t

x = a (cos t + sin t), y = a (sin t-cos t)

If x=a(cos t+t sin t) and y=a(sin t-t cos t)

If x=a(cos t+t sin t) and y=a(sin t-t cos t), then find (d^(2)y)/(dx^(2))

If x=a(cos t+t sin t) and y=a(sin t - t cos t), then (d^2y)/dx^2

If x=a(cos t+t sin t) and y=a(sin t-t cos t) , find (d^2y)/(dx^2)
