We can solve this quadratic equation by factoring to obtain ( y − 1) 2 = 0.
WebDec 20, 2024 · The Pythagorean identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan( − θ) = − tanθ. WebStep 1: Rearrange the equation to have the trig function on its own. Step 2: Calculate the value of your acute angle, using the inverse of your trig function.Note that the negative will always be ignored when calculating the acute angle. Step 3: Based on the sign of the function, determine the quadrants of the solutions and use the information from this to …
