What is a secant of a circle? Use the unit circle to find the six trigonometric functions of 7π/ 6. Use the unit circle to find the exact value of sec(13pi / 6). What are the six trig function values of 540 degrees? Use the angle in the unit circle to find the exact value ...
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=...

The ratios sine, cosine, and tangent are the "regular" trig ratios; the cosecant, secant, and cotangent are their respective reciprocal ratios (that is, the values of the flipped-over fractions for the "regular" ratios).By the way, there is no requirement that Greek letters be used as ...
TT = trigone-to-trigone distance, SL = septal-to-lateral distance, 2p = perimeter. Mitral cross-sectional area can also be directly measured. 5.2. Extent and location of mitral annular calcifications Mitral annular calcification (MAC) is a result of slowly progressive calcification...
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...
It was at least 2 miles more to Llanrhystud, and I was nervous about walking along the main A487 – it is a busy road, with no footpath. I decided that I would have to go back across the fields to the path, which I duly did, with little problem. I then came to the missing ...
