Find cos 30
WebCosine calculator Arccos definition. The arccosine function is the inverse function of … Web1st step. To find the steady-state current in the circuit, we need to first find the impedance of the circuit at the frequency of the input voltage, Vs (t) = 30 cos (200t) V. where R is the resistance, XL is the inductive reactance, and XC is the capacitive reactance. We can find these values as follows:

WebGoogle Classroom. Learn how to find the sine, cosine, and tangent of angles in right triangles. The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: WebExact values of sin(30), cos(30), tan(30), csc(30), sec(30), cot(30), Find exact values of …
Webtan (30°) = sin (30°) cos (30°) = 1/2 √3/2 = 1 √3 = √3 3 * tan (45°) = sin (45°) cos (45°) = √2/2 √2/2 = 1 tan (60°) = sin (60°) cos (60°) = √3/2 1/2 = √3 * Note: writing 1 √3 may cost you marks so use √3 3 instead (see Rational Denominators to learn more). Quick Sketch Another way to help you remember 30° and 60° is to make a quick sketch: WebFind the Exact Value cos(150) Step 1 Apply the reference angleby finding the anglewith equivalenttrig values in the first quadrant.

WebSolution Find the value of cos 15 °. We know that, cos 15 ° = cos 45 ° - 30 ° = cos 45 ° cos 30 ° + sin 45 ° sin 30 ° ∵ cos A - B = cos A cos B + sin A sin B = 1 2 3 2 + 1 2 1 2 Put cos 45 ° = 1 2, cos 30 ° = 3 2, sin 45 ° = 1 2 sin 30 ° = 1 2 = 3 2 2 + 1 2 2 = 3 + 1 2 2 Hence, the required value is cos 15 ° = 3 + 1 2 2 Suggest Corrections 87
