WebDec 1, 2015 · You end up with the values of sine 0,30,45,60 and 90. Drawing Sin Cos Tan Table. Step 5(orange):Once you have values for sine function, invert them for cosine i.e( sin 90 = cos 0, sin 60 = cos 30, sin 45 = cos 45 and so on) and you get values for cosine function. Step 6: For tangent, put sin/cos values and simplify. WebTo find (or recall) the trig values for 45° angles: Draw a 45-45-90 triangle with short sides having lengths of either (a) sqrt (2) or (b) 1. Label the hypotenuse as having a corresponding length of either (a) 2 or (b) sqrt (2). From whichever triangle you have drawn (either Triangle (a) or Triangle (b)), read off the trig ratio you need.
