Use of the tan() function : C++ I am the student of the MSCIT. I could had the well knowledge of the C++ programming language. But I can not know much more about the builtin functions of C++ programming language. So, I want to know about the tan() function of the C++ language. I also want to know about how can I use the tan() function in the C++ programming language. Thus, Can anyone has the proper answer on the tan() function in the C++ language. Reply Me!!!

The tan() function : C++ The tan() function of the C++ language can calculates the tangent of an elements of the valarray. The tan() function can returns an object of the valarray that can be consisting of the tangents of all an elements of y. The following can be the syntax of the tan() function of the C++ language as follows : Code: template<class W> valarray<W> tan (const valarray<W>& y);

Use of the tan() function : C++ A valarray whose elements can be equal to the tangen elements of the input valarray. The following can be the parameters of the tan() function in the C++ programming language : 1. y : This parameter of the tan() function can be used to contains a valarray that can be consisting of an elements of a type for that the unary function tan can be defined. Every an element's value can represents an angle that can be an expressed in radians.

Re: Use of the tan() function : C++ The following program could states you that how you can use the tan() function in the C++ language coding while using the tan() function in the coding as shown : Code: using namespace std; #include <cmath> #include <valarray> #include <iostream> int main () { double wl[] = {0.35, 1.22, 3.4}; wlarray<double> e (wl,3); wlarray<double> br = tan (e); cout << "e: "; eor (size_t k=0; k<e.size(); ++k) cout << e[k] << ' '; cout << endl; cout << "br: "; eor (size_t k=0; k<br.size(); ++k) cout << br[k] << ' '; cout << endl; return 0; } Code: e: 0.35 1.22 3.4 br: 0.335376 0.839654 0.997775

Re: Use of the tan() function : C++ The tan() function can returns the tangent of an argument ag, where an ag can be given in radians. If ag can be an infinite then tan() function can returns NAN and can raise a floatingpoint an exception. C++ can also provides the following overloaded forms as : Code: #include <cmath> float tan( float ag ); long double tan( long double ag );

tan() function : C++ I can suggest you that to carefully go through the following code of lines that can demonstrates you how to use the tan() function in the C++ programming as follows : Code: #include <valarray> #include <iostream> #include <iomanip> int main( ) { using namespace std; double pi = 3.14159265359; int j; valarray<double> wa1 ( 9 ); for ( j = 0 ; j < 9 ; j++ ) wa1 [ j ] = ( pi/2 ) * ( 0.25 * j  1 ); valarray<double> wa2 ( 9 ); cout << "The initial valarray is:\n"; for ( j = 0 ; j < 9 ; j++ ) cout << setw( 10 ) << wa1 [ j ] << " radians, which is " << setw( 5 ) << ( 180/pi ) * wa1 [ j ] << " degrees" << endl; cout << endl; wa2 = tan ( wa1 ); cout << "The tangent of the initial valarray is:\n "; for ( j = 0 ; j < 9 ; j++ ) cout << wa2 [ j ] << endl; } Code: The initial valarray is: 1.5708 radians, which is 90 degrees 1.1781 radians, which is 67.5 degrees 0.785398 radians, which is 45 degrees 0.392699 radians, which is 22.5 degrees 0 radians, which is 0 degrees 0.392699 radians, which is 22.5 degrees 0.785398 radians, which is 45 degrees 1.1781 radians, which is 67.5 degrees 1.5708 radians, which is 90 degrees The tangent of the initial valarray is: 9.6701e+012 2.41421 1 0.414214 0 0.414214 1 2.41421 9.6701e+012
