. How do you find the exact value of cos 180° - sin 180° degrees
Best Answer
Explanation:-
Use the values of cosπ and sinπ from the trigonometric ratio table to determine the value.
the value of
cos 180° =-1
sin 180° =0.
Therefore, on substituting the values of cos 180º and sin 180º in the equation,
⇒cos 180° - sin 180°
=-1-0
=-1
Final answer:-
Thus, the value of cos 180° - sin 180° is -1.
