physics  converting radians to degrees
i know how to convert degrees to radians.. ie: 40* x (2pi rad/360*) = 0.70 rad .. i cant figure out how to do the opposite.. can anyone show me how? thanks! ~lor .70 rad (360 deg/2PI rad )= 40o radians = degrees*2*pi/360 = 0.69813

I need help on finding the local linear approximation of tan 62 degree. i got 1.77859292096 can someone check if i got it right? tan(60+2) = (tan 60+ tan 2) / (1 tan60 tan 2) But tan2 appx = sin 2deg = sin2PI/180= 2PI/180 tan
