MHB Can You Solve This Tricky Trigonometric Floor Function Equation?

Click For Summary
The discussion revolves around solving the equation involving the floor function and trigonometric functions: {sin(⌊x⌋)} + {cos(⌊x⌋)} = {tan(⌊x⌋)} for real solutions. Participants clarify that the notation {x} represents the fractional part of x, defined as x - ⌊x⌋. There is also a question about whether x is measured in radians or degrees, with confirmation that x is in radians. The thread emphasizes understanding the fractional part in the context of the equation. Overall, the focus is on finding real solutions to the given trigonometric equation.

Solve $\{ \sin \lfloor x \rfloor \}+\{ \cos \lfloor x \rfloor \}=\{ \tan \lfloor x \rfloor \}$ for real solution(s).
 
x in radian or degree ?
 
Hi Kali, $x$ is in radian.

Sorry, but I'm a bit confused. I know what the floor function does but what does the {.} do?

Sorry Dan for not being clear in my question.(Blush)

{} means the fractional part of $x$, and defined by the formula $\{ x \}=x-\lfloor x \rfloor$.

Hope this clears it up!

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...
