How do you draw 45^circ and -45^circ in standard position and then show that cos(-45^circ)=cos45^circ? | Socratic
What equation/process do you need to know to find the exact value of trig expressions such as sin 45 + cos 60, my teacher only lectures and doesn't let us practice in
![SOLVED: Using the trigonometric identities, one can show that 166 cos(71x) cos(118 x) cos(4x) dx 83 cos(51 x) cos(43 x) cos(185 x) cos(193 dx 83 (cos(-50 x) cos( 42 x) cos(184 x) SOLVED: Using the trigonometric identities, one can show that 166 cos(71x) cos(118 x) cos(4x) dx 83 cos(51 x) cos(43 x) cos(185 x) cos(193 dx 83 (cos(-50 x) cos( 42 x) cos(184 x)](https://cdn.numerade.com/ask_images/f708093dc9334bf9a46dc04381a75d7c.jpg)
