what is integral of sin(2x) dx and sin(3x) dx

 

[Islu_jf]

I guess its
sin(2x) = -(1/2)cos(2x)

and same with the 2nd one.. not sure thou :S

thanks, but where the (1/2) comes?

 

[Islu_jf]

the coefficient of x ,

btw do u know this..
i really need help.. !!
yes guys i want questions.. please help..

I want to know how to find the postion vector..
i know it seems easy .. but my teacher never taught me vectors .. he was to busy trying to be a principle.. so i'm ******

i'll give an example in Question 7 OCT/NOV 2010 31.// Please.. ????

inetgrel of sin(3x) = -cos(3x)/3
and intg of sin(2x) = -cos(2x)/2
