WebbExample 1: Determine the value of the length of the base of a right-angled triangle if cos x = 0.8 and the length of the hypotenuse is 5 units using cosine function formula. Solution: We know that cos x = Base/Hypotenuse. We have cos x = 0.8, Hypotenuse = 5 units. Therefore, 0.8 = Base/5. ⇒ Base = 5 × 0.8 = 4. WebbFor the cosine it's a bit more complicated, try your hand at it. To turn to the “general” question: you want to prove that $$ \lim_{x\to a}\cos x=\cos a. $$ This is perfectly equivalent to proving that $$ \lim_{h\to 0}\cos(a+h)=\cos a. $$ Just try solving the necessary inequalities.
