How to solve an equation with sin and cos
WebJan 2, 2024 · If we have an equation in a slightly different form, we have to determine if there is a way to use algebra to rewrite the equation in the form y = Asin(B(t − C)) + D or y = Acos(B(t − C)) + D. Consider the equation y = 2sin(3t + π 2) Use a graphing utility to draw the graph of this equation with − π 3 ≤ t ≤ 2π 3 and. WebUse a calculator to solve the equation sinθ = 0.8 ,where θ is in radians. Solution Make sure mode is set to radians. To find θ, use the inverse sine function. On most calculators, you …
