dcole.ath.cx 0 Posted December 16, 2007 Report Share Posted December 16, 2007 Does it have inverse sin and inverse cos? tan = sin/cos and the same goes for inverse trig functions, so tan^-1 = (sin^-1) / (cos^-1)Other wise, remember that inverse tan is just tan with the X and Y switched.arctangent:y = arctan(x)x = tan(y) Domain: allRange:pi/2 < y < pi/2If that all fails, you could use a chart... If X = "this", then Y = "that" Quote Link to post Share on other sites
