Decibel calculator vs Circle Coordinate Calculator Usage & Stats

Sound levels are usually expressed in a logarithmic scale called the decibels (dB). The decibels cannot be added or subtracted directly. Each operation between decibel values requires to convert the sound level back to a linear scale using an antilog function. The dB calculator app allows the direct addition or subtraction of dB levels. The app uses the following formula: A + B = 10*LOG10(10^(A/10) + 10^(B/10)) For instance, 5dB + 5dB returns 8dB (3dB is added when doubling the sound level) or 1dB + 2dB = 4.5dB.

Circle Coordinate Calculator

Unit Circle Coordinate Calculator calculates the sine, cosine (x , y) values of any given angle. Features: • Calculates the sine, cosine (x , y) values of any given angle. • Calculates the slope (m) for the line. • Output the formula for the line. • Output the x coordinate and y coordinate by giving the new distance from origin. • Result is instant and copy-able. The Unit circle is a circle which is centered at the origin and which has the radius of 1 unit. It is represented by the equation: x² + y² = 1. The values of x and y are given by trigonometric functions as: x = sin θ y = cos θ So the value of sin θ and cos θ should such that the sum of their squares should be equal to 1. The Slope (m): m = change in y / change in x Equation of a straight line: y = mx Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
