Question

Let
f(x)=x^2tan^−1(3x)
When i did this problem i got
3x^2/1+9x^2
the correct answer is
2xtan^-1(3x)+3x^2/1+9x^2

Answer 1

What is the question?

Answer 2

ok were doing inverse trig functions
find the f(x)'

f(x)=\[x^2\tan^(-1)(3x)\]

Answer 3

you should use the product rule for differentiation. the two factors are x^2 and tan^-1(3x)

Answer 4

oh i'll try that thanks

Answer 5

thanks so much it worked
