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 ... WebMar 10, 2015 · This means that if you give a number to the arctangent function, most calculators respond with an answer between − 90 ∘ and 90 ∘. This is the half-plane on the right, quadrants I and IV, so x is assumed positive. If x is negative, the answer you want is 180 ∘ away. Share.

Slopes can be negative, therefore tangent values can be negative. As for cosines, if you believe the double-angle formula for cosine, apply it to a 60 ∘ angle, and see what happens! d0lweb fdacs.gov

"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. " - Can tan theta be negative
