The reciprocal identities arise as ratios of sides in the triangles where this unit line is no longer the hypotenuse. The triangle shaded blue illustrates the identity 1 + cot 2 θ = csc 2 θ {\displaystyle 1+\cot ^{2}\theta =\csc ^{2}\theta } , and the red triangle shows that tan 2 θ + 1 = sec 2 θ {\displaystyle \tan ^{2 ...
CAST still goes counterclockwise but starts in quadrant 4 going through quadrants 4, 1, 2, then 3. ACTS still starts in quadrant 1 but goes clockwise going through quadrants 1, 4, 3, then 2. Sines and cosines of special angles
In this right triangle, denoting the measure of angle BAC as A: sin A = a / c ; cos A = b / c ; tan A = a / b . Plot of the six trigonometric functions, the unit circle, and a line for the angle θ = 0.7 radians. The points labeled 1, Sec(θ), Csc(θ) represent the length of the line segment from the origin to that point.
Included are diagram techniques, chart techniques, plot techniques, and other forms of visualization. There is also a list of computer graphics and descriptive geometry topics . Simple displays

The bandeau top in this ZAFUL bikini ties in the front, which can give you a nice, line-free tan on your chest! 10. This simple ZAFUL string bikini set comes in incredible graphic prints!
Tan lines created by a bikini. Wearing a bikini in the sun results in the uncovered skin becoming suntanned and creates a "bikini tan". These tan lines separate pale breasts, crotch, and buttocks from otherwise tanned skin. [3] "Racing stripes" may refer to the portion of a bikini tan line exposed when wearing one-piece swimwear.
Tantalum nitride (TaN) is a chemical compound, a nitride of tantalum. There are multiple phases of compounds, stoichimetrically from Ta 2 N to Ta 3 N 5, including TaN. As a thin film TaN find use as a diffusion barrier and insulating layer between copper interconnects in the back end of line of computer chips. Tantalum nitrides are also used in ...
