Q. 9 ⋅ cos^2 ( θ ) + 9 ⋅ sin^2 ( θ ) = b. Sin is the ratio of the opposite side to the hypotenuse, cos is the ratio of the adjacent side to the hypotenuse, and tan is the ratio of the opposite side to the adjacent side. (ii) cos 8 ° - sin 8 ° cos 8 ° + sin 8 ° = tan 37 °.
Sin, cos, and tan are trigonometric ratios that relate the angles and sides of right triangles.6=sin(31)/3. Matrix
. ∴ tan5α =tan45°= 1. Note that means you can use plus or minus, and the means to use the opposite sign. Hence, we get the values for sine ratios,i., 0, ½, 1/√2, √3/2, and 1 for angles 0°, 30°, 45°, 60° and 90°.Explanation or the correct option: Solve the expression ( cos 9 ° + sin 9 °) ( cos 9 ° – sin 9 °) By Divide the numerator and denominator by cos 9°, we get.
