I have couple of problems that I am stuck with.(adsbygoogle = window.adsbygoogle || []).push({});

Hi,

Integration (tan(2x) dx limit pi/4 to 3 pi/4

When I intergrate this, I get ln [1/(sqrt(cos2x))]

So when put the limits, we have zero in the denominator. What do I do?

---------------------------------------------------------------------

The other problem is,

integration (1/(t-3) dt limit t to 3

With this one the problem is we have ln (0). What is the value of ln(0)?

Thannks fo r any help
