`int(e^(b)cos bx)dx=?`

int_(a)^(b)cos x dx

int e^(x)cos x*dx

int e^(x)cos e^(x)dx

int e^(ax)cos(bx+c)dx

If u=inte^(ax)sin " bx dx" and v=int^(e^(ax))cos " bx dx" ,then tan^(-1)((u)/(v))+tan^(-1)((b)/(a)) equals

If u=inte^(ax)sin " bx dx" and v=inte^(ax)cos " bx dx then "(u^(2)+v^(2))(a^(2)+b^(2))=

int(e^(x)+cos x)/(e^(x) +sin x) dx

int e^(ax)2^(bx)dx

int sin x*e^(cos x)dx

int(ax^(2)+bx+c)dx
