Y=e^x(acosx bsinx)
Y=e^x(acosx bsinx)-Answer (1 of 3) y = tan^1 (a cos x b sin x)/(b cos x a sin x) Divide numerator & denominator by b cos x y = tan^1 (a/b tan x)/ (1 a/b tan x) Taking a/b as tan c we have y = tan^1 tan (cx) y = cx So dy/dx = 1 Well, we also have x=Rcost and y=Rsint in addition to double angle identities, but I still can't seem to find satisfying algebraic justification for R's existence in f(x)= Rsin(xt) Please, help me figure it out Thanks Answers and Replies #2 tinytim Science Advisor
