Solve sinx=0.8 Microsoft Math Solver
WebJan 16, 2024 · Let's look at a graph of sinθ: graph {sinx [-6.25, 6.25, -2, 2]} This is sinθ with −2π < θ < 2π. We can see that sinθ = 1 at π 2 and will repeat each cycle of the graph. And so the answer is: θ = π 2 ± n2π where n is a natural number. Answer link. WebSolve for ? sin(theta)=1/2 Take the inversesineof both sides of the equationto extract from inside the sine. Simplify the right side. Tap for more steps... The exact value of is . The sinefunctionis positive in the first and secondquadrants. To find the secondsolution, subtract the reference anglefrom to find the solutionin the secondquadrant. WebPrecalculus. Solve for ? cos (3theta)=1. cos (3θ) = 1 cos ( 3 θ) = 1. Take the inverse cosine of both sides of the equation to extract θ θ from inside the cosine. 3θ = arccos(1) 3 θ = arccos ( 1) Simplify the right side. Tap for more steps... 3θ = 0 3 θ = 0. Divide each term in 3θ = 0 3 θ = 0 by 3 3 and simplify. normandy house
