Trigonometry
Inverse Sine Calculator
Find the angle whose sine equals a given value using the arcsine (sin⁻¹) function. Use this when solving triangles, physics problems, or any scenario where you know a sine ratio and need the corresponding angle.

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.
