31. The TAN Function Function Objective: The TAN function is applied to return the tangent of the given angle. Syntax: =TAN(number) Arguments Explanation: ArgumentRequired/OptionalExplanation number Required A real number as an angle. Return Parameter: The tangent of a number. Use of TAN...
cos(x)= c1 + x2(c2 + x2(c3 + x2(c4 + x2(c5 + x2(c6 + x2(c7 + x2(c8 + x2(c9 + x2(c10 + x2*c11))) Tangent The tangent of an angle is defined astan(x)=sin(x)/cos(x). Unhappily this is not the best choice, though, for doing an approximation. As cos(x)...
