hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

this is a question i got really confused on

they give you a question which is 3=ln(t) * sin(t)

solve for t. i dont know how to do this algebracially if it is even possible. i can do it on my calculator by sketching the graph and finding the exact value but how do you do this algebracially?.

The best i can get is ln(t) = 3/sin(t) but still i cant solve lol.

2. find the derivative of y=ln(t) * sin(t) i used the product rule and got

U=ln(x)

u`=1/x

V=sin(x)

v`=cos x

Dy/dx= ln(x)* cos(x) + sin(x)/x

if i let dy/dx=0 how do i solve for x?
