Frequently Asked Questions (FAQ)
Degrees and radians are two different units for measuring angles. Degrees divide a circle into 360 equal parts, while radians divide a circle into 2π (approximately 6.283) equal parts. Trigonometric functions like sin, cos, and tan give different results depending on whether the input is in degrees or radians. Most scientific calculators allow you to switch between these modes. For everyday use, degrees are more common, but radians are standard in higher mathematics and physics.
To calculate exponents, use the x^y or ^ button. For example, to calculate 2³, enter “2”, press “x^y”, enter “3”, then press “=”. To calculate roots, use the √ button for square roots or the ʸ√x button for nth roots. For example, to calculate the cube root of 8, you would use the ʸ√x function: enter “3”, press “ʸ√x”, enter “8”, then press “=” to get 2.
