WebDec 2, 2024 · And if you cannot figure out how to implement it with fminsearch, then it is trivially simple to just solve the second equation for t, then substitute into the first equation. t = 6248/ (460*sin (theta)) When you eliminate t in the first equation, you now have a simple equation, solvable using fzero. WebOct 17, 2024 · Hello, currently I tried to use matlab for solving the equation based on van Genuchten model I would like to find alpha and n value by inputting hundred 141 sets of theta and psi values What i hope to do is to compare two sets of inputs theta and psi values.The equation I created becomes the following:

WebNov 28, 2024 · Solve for b to the nearest tenth. Figure 4.34.4 Solution First, take the given lengths and substitute them into the formula. 42 + b2 = 122 16 + b2 = 144 Next, subtract 16 from both sides of the equation. 16 − 16 + b2 = 144 − 16 b2 = 128 Then take the square root of both sides of the equation. b = 11.3137085… Round to the tenths place b ≠ 11.3 WebNov 3, 2024 · and conclude that the general solution becomes θ 1 = arctan ( a c a a 2 + b 2 − c 2) − arctan ( b a) + 2 π k 1 θ 2 = − arctan ( a c a a 2 + b 2 − c 2) − arctan ( b a) + π ( 2 k 2 + 1) where k 1, k 2 ∈ Z and a ≠ 0.

Webcos (θ²) + sin (θ²), then that is NOT equal to 1, except for a few special angles such as θ=√ (2π), θ=0 or θ= ½√ (2π) If you mean: (cos θ )² + (sin θ)² = 1 Which is usually written as: cos² (θ) + sin² ( θ) = 1 Then that is true.
