Trigonometric Angles

Trigonometric Angles

Trigonometric angles are very easy to learn if u follow some of these steps-

From the table ,just learn the values of sinθ upto 90 and now see that as now move from left to write in sinθ,the same values will come when you move from right to left in cosθ.Now the next column is of tanθ,we know that tanθ=sinθ/cosθ,so we can easy calculate by dividing sinθ and cosθ.Then next we move on to cotθ,which can be find out by doing inverse of tanθ or by dividing cosθ and sinθ,as cotθ=1/tanθ or cotθ=cosθ/sinθ.now go to secθ,it is reciprocal of cosθ,cosθ=1/cosθ,and at the end it is cosecθ,which can be find out by finding reciprocal of sin's value,as cosecθ=1/sinθ.
Angles can be complementary angles and complex angles
