Question 1

What functions does this scientific calculator support?

Accepted Answer

It supports sin, cos, tan, asin, acos, atan, log₁₀, ln, sqrt, factorial, powers, π, e, memory storage (M+, M−, MR, MC), and a 20-entry calculation history.

Question 2

How do I switch between degrees and radians?

Accepted Answer

Click the DEG/RAD toggle in the display area. When set to RAD, trig functions (sin, cos, tan) use radians; when set to DEG they use degrees.

Question 3

What does the ANS button do?

Accepted Answer

ANS inserts the result of your last calculation into the current expression, letting you chain operations without retyping the previous result.

Question 4

How do I use memory functions?

Accepted Answer

Use M+ to add the current result to memory, M− to subtract it, MR to recall the stored value into the expression, and MC to clear memory.
