$\cos\left(a+45\right)=\frac{\sqrt{2}}{6}$
Learn how to solve differential calculus problems step by step online. Prove that cos(a+45)=(2^1/2)/6 is not an identity. Calculate the square root of 2. Divide 1.4142 by 6. This equation has no solutions in the real plane. There is no identity or mathematical rule that allows us to proceed trying to match both sides of the equality, so we conclude that it is not true.
