WebFeb 10, 2024 · c² = a² + b² - 2ab × cos (γ) For a right triangle, the angle gamma, which is the angle between legs a and b, is equal to 90°. The cosine of 90° = 0, so in that special case, the law of cosines formula is … WebThe sine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the opposite side to the longest side of the triangle. In the illustration below, sin (α) = a/c and sin (β) = b/c. From cos (α) = a/c follows that the sine of any angle is always less than or equal to one.

WebThus, you multiply both sides of the equation by DG" DG sin (72) = 8.2 "Again because we're solving for DG, we have to isolate DG so that it alone is on the left side of the equation. To do so, we have to move sin (72) to the other side, or in other words divide both sides of the equation by sin (72)." DG = 8.2/sin (72) "Now use the calculator" WebSine, Cosine and Tangent are the main functions used in Trigonometry and are based on …
WebExplanation: For cos 12 degrees, the angle 12° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 12° value = 0.9781476. . . ⇒ cos 12° = cos 372° = cos 732°, and so on. Note: Since, cosine is an even function, the value of cos (-12°) = cos (12°).
