Thank you!

For y sec(x) = 3x tan(y), the direction above it says "Regard y as the independent variable and x as the dependent variable and use implicit differentiation to find dx/dy." I do now know if that makes any different and I believe I have 4 lives left. For the x3 + y3= ...

Calc
Thank you! For y sec(x) = 3x tan(y) I got dy/dx = (3 tan(y) - y tan(x)sec(x)) / (sec(x) - 3x sec²(y)) but it was still incorrect... I have no idea how to do y = arctan[(sqrt((1 + x)/(1 - x)))] because i never did this type of problem before, help please. here is another p...

Thank for replying =D. Unfortunately, I have been using implicit differentiation and I do not fully understand the logarithm. I am still getting an incorrect answer. Please show me an example on how to solve these problems. Thank you.

Can anyone help me find the derivative of these functions? y = x^2x y = x^-cos(x) y = ln(7x^2 + 5y^2) sqrt(3x+y)=2+x^2y^2 ysec(x) = 3xtan(y) y = arctan[(sqrt((1 + x)/(1 - x)))]
