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

Webcosecant, secant, and cotangent are basically flipping the fractions which is called reciprocal. E.g: 3/5 is turned into 5/3 when reciprocated. cos-1, sin-1, and tan-1 are when you use the same fractions but reverse their purpose. E.g: you use cos (55°) to find the side length and in another case you use cos-1(2/4) to find a missing angle. blackwoods wollongong phone numberWebSection 3-4 Chain Rule Practice Calculus I Find the derivative of each function. 1. y = sin(3x + 1) √ 2. y = cos 3x 2 2 4.
