WebFeb 23, 2015 · The first step is to stop and think about the problem itself. What is the cosine? If you recall, the formula for cosine (remember SOHCAHTOA?) is adjacent over hypotenuse. So, with your $\frac{1}{3}$ example, $1$ represents the length of the adjacent side, and $3$ represents the hypotenuse. inclined load tests on shallow strip footingsWebMar 5, 2024 · Explanation: To find value of sin(cos−1(1 2)) Let theta = cos^-1 (1/2)#. cosθ = (1 2) We know, from the above table, cos60 = 1 2. Hence theta = 60^@#. Replacing cos−1(1 2) with θ = 60∘, The sum becomes, ⇒ sinθ = sin60 = √3 2 (As per table above) Answer link. inclined length formulaWebThis calculator can solve basic trigonometric equations such as: $\color{blue}{ \sin(x) = \frac{1}{2} }$ or $ \color{blue}{ \sqrt{2} \cos\left(-\frac{3x}{4}\right) - 1 = 0 } $.
