a table of values of trigonometric functions sine 45, cosine 45, tangent 45 degrees, sin 45, cos 45, tg 45 and an explanation of the calculation of these values.

Thus for example the entry "45°: square" means that, with n = 4, 180° ÷ n = 45°, and the number of degrees in each angle of a square is (n – 2) × 45° = 90°. 0°: fundamental [ edit ] sin ⁡ 0 = 0 {\displaystyle \sin 0=0\,} Find the exact value of: \sin 45^{\circ}+\sin 135^{\circ}+\sin 225^{\circ}+\sin 315^{\circ} "Exact value" means you leave the answer just like this rather than finding a decimal approximation. Again, a 30/60/right triangle has sides with ratio 1:√3:2. The 60 degree angle has the √3 side opposite and the 1 side adjacent, and the 2 side is still the hypotenuse.

The exact value of sin(45°) sin (45 °) is √2 2 2 2. √2 2 2 2 The result can be shown in multiple forms.

4) sin 25° cos 35° + COS 25° sin 35° Solve the equation on the interval [0, 276). 5) COS X + 2 cos x sin x = 0 Solve the triangle using the Law of Sines. 6) 45°A Use the Pythagorean Theorem to find the length of the missing side.

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.
