WebJul 1, 2024 · For this one, you’ll use the ratios for a 45-45-90 triangle. It has sides of 1 and a hypotenuse of √2. So if plotted on a unit circle, the basic trig functions are: sinπ/4 equals 1/ (√2) cosπ/4 equals 1/ (√2) tanπ/4 equals 1. cscπ/4 equals √2. …
WebThe radian is an SI unit that helps in the measurement of the angles. Moreover, it is also the standard unit for angular measurement that we use in various areas of mathematics. The unit circle’s length of an arc is … WebOne revolution covers 2 π radians (or 360 degrees), and therefore has an angle of rotation of 2 π radians, and an arc length that is the same as the circumference of the circle. We can convert between radians, revolutions, and degrees using the relationship 1 …
WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps! ( 9 votes) Flag
WebThe circumference of a circle is C = 2πr.
