thank you very much n!kofeyn , really appreciate your help

thanks for the heads up I did the product rule part and natural log differentiates differently from normal differentiation is it ? from the question above : f(r,s,t) = r ln (rs^2t^3) i differentiate fr first i get r(s^2t^3) ------------ + lnrs^2t^3 rs^2t^3 is this right ? i am doing...

i have double checked my notes and i see that for continuous functions either way is applicable . but for this i believe starts from fr to frs then frss . the final answer for frss should be -2s^-2 thanks

some help with this differentiation question thanks Question : Find the indicated partial derivative . frss , frst f(r,s,t) = r ln (rs^2t^3) differentiating with respect to r gave s^2t^3 1* ---------- rs^2 t^3 but this is not correct something is...

Homework Statement how can i convert this : - 2 (cos pai / 4 + i sin pai / 4 ) to Cartesian , Polar and Exponential form ? Homework Equations z = ( a + i b) The Attempt at a Solution r= -2 tan inverse = pai/4 / pai/4 ?? Thank you very much for helping me out

Express -2(cos pai/4+i sin pai/4 ) in Cartesian , Polar and Exponential form ? how can i convert this : - 2 (cos pai / 4 + i sin pai / 4 ) to Cartesian , Polar and Exponential form ? Thank you very much
