Question

find dy/dx, x= a ( costheta + thetasintheta ), y = a (sintheta + thetacostheta)
plz ans correctly and dont spam .... its similar to class 12th book ques but the signs are diff​

Answer 1

Answer:

Tan θ

Step-by-step explanation:

Given  x= a ( costheta + thetasintheta ), y = a (sintheta + thetacostheta)

dy / d thetha = a(cosθ−cosθ+θsinθ)=a(θsinθ)

Similarly , we get  dθ / dx  = a(−sinθ+sinθ+θcosθ)=a(θcosθ)

⟹ dy / dx = aθsinθ / aθcosθ = tanθ
