What is the tangent of an angle?Trigonometric Functions:Sine, cosine, and tangent functions are at the heart of the study of trigonometry. We can define each of these functions using the sides and angles in a right triangle, where a right triangle is one containing a 90° angle....
Specifically, the cosine looks just like the sine, but shifted a bit to the left; the cosecant is a left-shift of the secant; the cotangent is the tangent after flipping it upside-down and then shifting the result a bit to the left. How did the trig ratios get their names? The trig...

Relative velocity would be like vrel/c=tanh(θB−θA)=1cvB−vA1−vBvA (which is invariant of choice of inertial frame). In Galilean spacetime trigonometry, using Yaglom's Galilean trig functions (cosgη=1; singη=η, and tangη=singηcosgη=η, relative velocity is vrel/c=...
At the farthest point of Dinas Head, is the trig point, painted with the slogan ‘Cofiwch Dryweryn’ a reference to the outrageous drowning of the village of Tryweryn in Gwynedd by Liverpool Council in 1965 to create a reservoir to supply the city. Just after Dinas Head, we came to ...
The &"+x*0" part of the chtY definition works around an error in Excel that sometimes causes trig functions to not evaluate as array formulas, by forcing the entire formula to be evaluated as an array. Faking It A chart is a visual artifact, designed to impart information to the viewer...
when ##\lambda## is in-between, then ##(x,y,z)## is a point on the beam in between A and C. It will get you your answer very directly. If you use pythagoras and maybe some trig - then you want to construct the triangle OAC - sketch it out. (point O b...

Past half way, outward on the ring means downward on it, so the only section where the force on the ring can be upwards is in some range above the halfway mark. It's not a sudden change. Somewhere before the angle you found (maximising the upward force on the ...
