They are both trig values, but not equal. Tan 45 is 1 and sin 45 is 0.7071

y = sin x, or y = cos x etc. can be graphed by making a table of values. The x column in the table would be angle measurements (usually in degrees or radians) and the y column would be the trig. function value. Then plot the points and sketch the curve going thru those points. Ex: for y = sin x x , y 0 0 30 0.5 45 0.707 etc and then graph these
yeah. a sin is still a sin.
It is: sin(62) = 0.8829475929.
It is:- sin(40) = 0.6427876097
