simult(coeffMatrix, constMatrix[, tol]) ⇒ matrix Solves multiple systems of linear equations, where each system has the same equation coefficients but different constants. Each column in constMatrix must contain the constants for a system of equations. Each column in the resulting matrix contains the solution for the corresponding system. Solve: x + 2y = 1 x + 2y = 2 3x + 4y = ë 1 3x + 4y = ë 3 simult([1,2;3,4],[1,2;ë 1,ë 3]) ¸ [ë2 3 9ë/27] For the first system, x=ë 3 and y=2. For the second system, x=ë 7 and y=9/2. sin( ) W key sin(expression1) ⇒ expression sin(list1) ⇒ list sin(expression1) returns the sine of the argument as an expression. sin(list1) returns a list of the sines of all elements in list1. Note: The argument is interpreted as a degree, gradian or radian angle, according to the current angle mode. You can use ó ,G o r ô to override the angle mode setting temporarily. In Degree angle mode: sin((p/4)ô ) ¸ sin(45) ¸ sin({0,60,90}) ¸ In Gradian angle mode: sin(50) ¸ ‡2 2 ‡2 2 {0 ‡3 2 1} ‡2 2 In Radian angle mode: sin(p/4) ¸ ‡2 2 sin(45¡) ¸ ‡2 2 sin(squareMatrix1) ⇒ squareMatrix Returns the matrix sine of squareMatrix1. This is not the same as calculating the sine of each element. For information about the calculation method, refer to cos(). squareMatrix1 must be diagonalizable. The result always contains floating-point numbers. In Radian angle mode: sin([1,5,3;4,2,1;6,ë 2,1]) ¸ .ë9.4024...5... ë.045... .949... ë.031... ë.020...   ë.048... ë.005... .961...  sinê () 2 Q key sinê (expression1) ⇒ expression sinê (list1) ⇒ list sinê (expression1) returns the angle whose sine is expression1 as an expression. sinê (list1) returns a list of the inverse sines of each element of list1.
