Interior angles A, B, and C of a plane triangle are known and fixed. The area of the triangle is computed from these angles and the measured value of side a (opposite angle A). Show that the relative error in the computed area is twice the relative error in the measured side.

mathswithmuza on Instagram: "Trigonometric functions are mathematical relationships that connect the angles of a triangle with the ratios of its sides. The most common ones are sine, cosine, and tangent, which are defined using right triangles. For example, sine measures the ratio of the side opposite an angle to the hypotenuse, while cosine measures the ratio of the adjacent side to the hypotenuse. These functions are not limited to triangles; they are used to describe patterns of waves, oscill
