WebThe arclength in the x-y plane is ALWAYS ∫ √ ( dx² + dy²). Thus, if you are given x (t) and y (t) (we say "parametric" equations for x and y), then we can write this as: L = ∫ √ ( (dx/dt)² + (dy/dt)² ) dt Basically, we have "divided" everything inside the radical by dt², and so we then multiply on the outside of the radical simply by dt. WebThe piece of information we are missing to solve for arc length is the radius, so we will use the formula for finding the area of a sector to solve for radius, allowing us to solve for the arc length. Now we can plug this into our formula to solve for arc length

When the tangent of y is equal to x: tan y = x Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x = tan -1 x = y Example arctan 1 = tan -1 1 = π/4 rad = 45° Graph of arctan Arctan rules how to troubleshoot a blank screen
