Evaluate the sine cosine and tangent of the angle without us
Evaluate the sine, cosine, and tangent of the angle without using a calculator. (If an answer is undefined, enter UNDEFINED.) 225 degree Evaluate the sine, cosine, and tangent of the angle without using a calculator. (If an answer is undefined, enter UNDEFINED.) 300 degree
Solution
225 deg
180 +45 = 225
sin(180+45) = -sin45
= -1/sqrt2
cos(180+45) = -cos45
= -1/sqrt2
tan(180+45) = tan45
= 1
300 = 360 -60
sin(360 -60) = -sin60 = -sqrt3/2
cos(360 -60) = cos60 = 1/2
tan(360 -60) = -tan60 = -sqrt3
