How To Find The Values Of Trigonometric Functions Given Information About An Angle Trigonometry Study Com
Web Explanation A rightangled triangle with angles of 60° and 30° has sides in the ratio 1√32 The core angle of √3 2 is 60° However, the negative sign indicates that weSin (x)= ( square root of 3)/2 sin(x) = √3 2 sin ( x) = 3 2 Take the inverse sine of both sides of the equation to extract x x from inside the sine x = arcsin( √3Web tan 60° = tan∠CAD = p/b = AD/CD = (√3k/2)/ (k/2) = √3 Also, cosec 60°, sec 60°, cot 60° being the reciprocal of sin, cos, tan respectively will have just the reciprocal
Web Once filled, the values in the cosine column should be 1, √3/2, 1/√2, ½, and 0 4 Divide your sine values by the cosine values to fill the tangent column Simply speaking,Web2 = r 1cos 1 cos Other Useful Trig Formulas Law of sines 33 sin = sin = sin Law of cosines 34 a2 = b2 c2 2 b c cos b2 = a2 c2 2 a c cos c2 = a2 b2 2 a b cos Area of triangle 35Web Write the expression in terms of common angles We know the cosine and sine of common angles like and It will therefore be easier to deal with such angles 2 3 Use the
