Web1 okt. 2024 · Firstly we have to find the value of AC. So, we can find the value of AC with the help of Pythagoras theorem ⇒ (AB)2 + (BC)2 = (AC)2 ⇒ (3k)2 + (4k)2 = (AC)2 ⇒ (AC)2 = 9 k2+16 k2 ⇒ (AC)2 = 25 k2 ⇒ AC =√25 k2 ⇒ AC =±5k But side AC can’t be negative. So, AC = 5k Now, we will find the sin θ and cos θ Side opposite to angle θ = AB = 3k Web20 dec. 2016 · There’s a very cool second proof of these formulas, using Sawyer’s marvelous idea.Also, there’s an easy way to find functions of higher multiples: 3A, 4A, and so on.
