mathswithmuza on Instagram: "Trigonometric functions describe the relationships between the angles and sides of a triangle, particularly a right-angled triangle. The six main trigonometric functions are sine, cosine, tangent, cosecant, secant, and cotangent. Each of these functions relates an angle to specific ratios of the triangle’s sides—for example, the sine of an angle is the ratio of the opposite side to the hypotenuse, while the cosine is the ratio of the adjacent side to the hypotenuse.
