WebAnother precarious convention used by a tiny number of authors is to use an uppercase first letter, along with a −1 superscript: Sin −1 (x), Cos −1 (x), Tan −1 (x), etc. Although its intention is to avoid confusion with the multiplicative inverse, which should be represented by sin −1 (x), cos −1 (x), etc., or, better, by sin −1 x ... WebTherefore, SIN/COS = TAN/1 . You can also see that 1/COS = SEC/1 and 1^2 + TAN^2 = SEC^2. A bunch of those almost impossible to remember identities become easier to remember when the TAN and SEC become legs of a triangle and not just some ratio of other functions. The angle line, COT line, and CSC line also forms a similar triangle.

WebSine, cosine and tangent are the primary trigonometry functions whereas cotangent, secant and cosecant are the other three functions. The trigonometric identities are based on all the six trig functions. ... Consider two angles , α and β, the trigonometric sum and difference identities are as follows: sin(α+β)=sin(α).cos(β)+cos(α).sin(β) WebJan 2, 2011 · Whereas the law of Cosine is used to calculate the side of that triangle, whose one angle and two sides are known. • As 2 π radian = 360 degree, so if we want to calculate the values of Sin and Cos for angle greater than 2 π or less than -2 π, then Sin and Cosine are periodic functions of 2 π. Like. Sin θ = Sin (θ + 2 π k) enameled cast iron loaf pan
