The Significance of the Unit Circle in Trigonometric Functions
Significance of Quadrants in Trigonometry All functions are positive Sine and cosecant are positive Tangent and cotangent are positive Cosine and secant are positive. Coordinates on the Unit Circle Any angle, corresponds to a specific point on the circumference of the unit circle. The x-coordiante of that point is the cosine value of that angle, […]
Understanding Trigonometry: How to Calculate the Area of Triangles
Examples Practice Questions: Given triangle \(XYZ\) with \(XY = 6 \text{ cm}\), \(YZ = 9 \text{ cm}\), and angle \(Y = 30^\circ\), find its area. For triangle \(LMN\), if \(LM = 4 \text{ cm}\), \(MN = 5 \text{ cm}\), and angle \(M = 90^\circ\), calculate the area. \( 13.5 \text{ cm}^2 \) \( 10 \text{ […]
