Type any expression using sin, cos, tan, log, ln, sqrt, ^, pi, e — evaluated safely.
Standard operator precedence with trigonometric, logarithmic and exponential functions.
sin(pi/4) + sqrt(2) ≈ 0.7071 + 1.4142 = 2.1213.
An online scientific calculator handles everything a physical TI-30 can — plus you can bookmark it and copy results directly. Ideal for homework, engineering estimates and quick physics.
Yes — use pi/2 for 90°.
log = base 10, ln = natural log.
