Question

Solve : 2px = 2 tan y +p³ cos² y.​

Answer 1

Answer:

2px()23

Step-by-step explanation:

so answer is 30 because it is cos thita

Answer 2

Answer:

dy/dx = 2p/2sec²y-p³sin2y+3p²cos²y

Step-by-step explanation:

Given, 2px = 2tany+p³cos²y

Take derivative on both sides with respective of x

2p dx/dx = d/dx(2tany) + d/dx(p³cos²y)

2p = 2 sec²y dy/dx +[ p³(-sin2y dy/dx) +

cos²y3p² dy/dx

Hence,

dy/dx = 2p/2sec²y - p³sin2y + 3p²cos²y
