Values such as sin75 degrees, cos75 degrees, tan75 degrees, etc. Based on the above results, you can also find values such as $\sin 75^ {\circ}$ and $\sin 105^ {\circ}$. Use this when you want to know the sine, cosine, tangent, and radian values for angles. After the table, we will introduce the definitions of trigonometric functions and conversion formulas based on periodicity and symmetry.
