MHB Find angle in radians of tractor wheel going 22 mph in 12 s

Click For Summary
To find the angle in radians for a tractor wheel moving at 22 mph over 12 seconds, the discussion emphasizes using angular equations instead of linear ones. The formula v = rω is highlighted, where ω (angular velocity) is calculated by converting the linear speed to radians per second. The angle θ is then determined using the equation θ = ωt. The importance of unit conversions is also noted to ensure accuracy in calculations. This approach provides a systematic method for solving the problem.

the calculation is mine however, if ans is correct not sure what the conventional way would to set this up?

I typically would include the actual formulas you are using. I also tend to use the angular equations rather than trying to use the linear ones. For example: [math]v = r \omega[/math], so [math]\omega = \frac{v}{r}[/math] (And at this step you would do your unit conversions.)

Then you simply have [math]\theta = \omega t[/math].

Thread 'Erroneously  finding discrepancy in transpose rule'
Obviously, there is something elementary I am missing here. To form the transpose of a matrix, one exchanges rows and columns, so the transpose of a scalar, considered as (or isomorphic to) a one-entry matrix, should stay the same, including if the scalar is a complex number. On the other hand, in the isomorphism between the complex plane and the real plane, a complex number a+bi corresponds to a matrix in the real plane; taking the transpose we get which then corresponds to a-bi...
