WebWell we can just read the graph right over here. It equals one, so cosine of theta equals one, cosine of theta equals one at, at theta is equal to, well, we see it right over here. Theta is equal to zero, theta is equal to, well we've gotta go all the way again to two pi, two pi, but then it just keeps going on and on, and it makes sense. WebIf 3 sin θ +4 cosθ =5, then the value of sin θ is .

WebFree math lessons and math homework help from basic math to algebra, geometry and beyond. Students, teachers, parents, and everyone can find solutions to their math problems instantly. WebApr 7, 2024 · Each of these angles has different values with different trigonometric functions. Note: 1 cos theta = 1. Cos θ; Eg: 1 cos 30° = 1. Cos 30° = 1 x √3/2 = √3/2. Also, sin (90 - θ) = cos θ and Cos (90 - θ) = sin θ. Also remember sin 45 = cos 45 = 1/√2. The value of sin θ and cos θ can never be greater than 1.
