Trigonometry
Triangle Area Calculator
Calculates the area of any triangle from two sides and the included angle (the SAS formula): A = ½·a·b·sin(C). Perfect for surveying, navigation, and engineering tasks where the perpendicular height isn't directly available but two sides and the angle between them are known.
Fill in the required fields to see your result.
Trigonometry
Sine Calculator
Calculates the sine of an angle entered in degrees, returning a value between −1 and 1. Use it when solving right triangles, decomposing vector components, modeling waves, or working through trigonometry homework.
