We will first look into the trigonometric functions of the angles 30°, 45° and 60°. Let us consider 30° and 60°. These two angles form a 30°-60°-90° right triangle as shown. The ratio of the sides of the triangle is. 1 : √3 : 2. From the triangle we get the ratios as follows: Next, we consider the 45˚ angle that forms a 45°-45°-90. cos. . ( 45 ∘) = 1 2. Actually, the cosine of angle 45 degrees is an irrational number and its exact value can be written in decimal form as follows. cos. . ( 45 ∘) = 0.7071067812 .

In short, it shows all the possible angles which exist I've already made videos on the arc arc sine and the arc tangent so to kind of complete the trifecta I might as well make a video on the arc cosine and just like the other inverse trigonometric functions the arc cosine it's kind of the same thought process if I were to tell you that the arc now I'm doing cosine if I were to tell you that the arc cosine of X is equal to theta this is an. For any right triangle, there are six trig ratios: Sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Here are the formulas for these six trig ratios: Given a triangle, you should be able to identify all 6 ratios for all the angles (except the right angle). Let's start by finding all 6 ratios for angle A. We know that cos (a-b) = cos a * cos b + sin a *sin b cos 15 = cos (45-30) => cos 15 = cos 45 * cos 30 + sin 45 * sin 30 => cos 15 = (1/√2)* (√3/2) + (1/√2.
