WebANS : To transform from the original xy orientation to Orientation 1, we need to rotate the stress tensor counterclockwise by an angle of theta. Based on the given values in the image, we can use the formula tan (2 theta) = 2 tau/ (sigma_x - sigma_y) to solve for theta. Substituting the values of tau, sigma_x, and sigma_y, we get tan (2 theta ... Web... and yes, there are lots of others - technically, an infinite number of others since sin and cos are periodic and repeat every 2pi, positive or negative. So, for example, sin (θ)=sin (θ+2npi), where n is any integer. I'd probably add to the list: sin (-θ)=-sin (θ) cos (-θ)=cos (θ),

WebDec 20, 2024 · We can interpret the tangent of a negative angle as tan( − θ) = sin( − θ) cos( − θ) = − sinθ cosθ = − tanθ. Tangent is therefore an odd function. The cotangent identity, cot( − θ) = − cotθ, also follows from the sine and cosine identities. We can interpret the cotangent of a negative angle as cot( − θ) = cos( − θ) sin( − θ) = cosθ − sinθ = − cotθ.
