Find the exact value of $\ EXACT VALUES OF TRIGONOMETRIC FUNCTIONS OF WIDELY USED ANGLES. Let us list out the values of trigonometric functions at known angles. (i) The values given above are all exact. (ii) We observe that sin 30 Find the value of sin 2 45 Find the exact value of: \sin 45^{\circ}+\sin 135^{\circ}+\sin 225^{\circ}+\sin 315^{\circ} 2010-01-05 2021-04-05 sin(45 degrees) = 1 / √(2) We can see that whether we use the right triangle only or the unit circle, we get the same answer. Since trigonometry means the measurement of triangles, you may have wondered so far why we use the unit circle to do trigonometry. Question: Sin 45 Remember To Use A Degree Symbol. Find Its Exact Value.

Note down the pattern from sin 0 to sin 90: Hence, we can now fill all sin values in the table. Now, we will fill all the cos values. Exact Trigonometric Function Values What angles have an exact expression for their sines, cosines and tangents? You might know that cos (60°)=1/2 and sin (60°)=√3/2 as well as tan (45°)=1, but are 30, 45 and 60 the only angles up to 90° with a formula for their trig values?
