How do you solve sin2x plus 3 cos 2x equals 0?
sin2x + 3*cos2x = 0sin2x = -3*cos2x
tan2x = -3
2x = arctan(-3)
x = 0.5*arctan(-3) in the domain which should have been specified. As none has, the question has no answer.

What is the derivative of 5x 3xexp-1?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y)2.
There is no operator between 5x and the next "term".
