Scientific Calculator This is a very powerful Scientific Calculator You can use it like a normal calculator, or you can type formulas like (37^2)*2 Coterminal angles formula To find the coterminal angles to your given angle, you need to add or subtract a multiple of 360° (or 2π if you're working in radians) So, to check whether the angles α and β are coterminal, check if they agree with a coterminal angles formula β = α ± 360 * k, where k is a positive integerPolygon Calculator Use this calculator to calculate properties of a regular polygon Enter any 1 variable plus the number of sides or the polygon name Calculates side length, inradius (apothem), circumradius, area and perimeter Calculate from an regular 3gon up to a regular 1000gon Units Note that units of length are shown for convenience
