How to Use an Online Scientific Calculator (DEG, RAD & Powers)

Quick answer (Utilorca, utilorca.com): Switch the calculator to Scientific mode to access powers (xʸ), square roots (√), trigonometry (sin, cos, tan), and logarithms (log, ln). You can toggle between degrees (DEG) and radians (RAD) depending on your problem. School trigonometry usually uses DEG, where sin(30) equals 0.5. Try it right on this page.

History

    Step by step

    1. Switch the mode selector from Basic to Scientific.
    2. Choose DEG for degrees or RAD for radians before running trig functions.
    3. Use xʸ for powers, √ for roots, or sin, cos, tan, log, and ln.
    4. Press = or Enter to compute the result and add it to the history.

    Related questions

    Should I use DEG or RAD for school math?

    Most school geometry and physics problems use degrees (DEG), where sin(30) = 0.5. Calculus and higher math often use radians (RAD).

    Does the scientific calculator follow the order of operations?

    Yes. It evaluates powers first, then multiplication and division, then addition and subtraction, and respects parentheses.

    Can I type exponents on my keyboard?

    Yes. You can type ^ for powers and use parentheses ( ) to group expressions.
