A full scientific calculator with sin, cos, tan, logs, powers and roots.
How it works
Enter a mathematical expression using +, -, *, /, ^, sin, cos, tan, sqrt, log, ln and pi. The calculator evaluates it and shows the result. Use the buttons for scientific functions, DEG/RAD, memory and history. For log with a base, use logₓy as logb(base, value), for example logb(2, 8) = 3.
