使用 +, -, *, /, ^ 等运算符来进行加减乘除和幂运算。例如，输入 sin(pi/4)^2 + cos(pi/4)^2 并按回车键，您会看到以下结果：使用 subs 函数来替换符号变量或表达式中的值。例如，输入 subs(y,x,pi/6) 并按回车键，您会看到以下结果：使用 simplify 函数来简化符号表达式或方程。例如，输入 simpl...
Simplify cos(x) + sin(x)tan(x). Trigonometric Functions: The relations between the sides and angles of a right-angled triangle give us important functions that are used extensively in mathematics. Additionally, these are called trigonometric functions. ...
How to find sin(x) given sec(x)? Does secx = cos^{-1}x? How do you simplify 1 + sec^2(x)? How do you prove (tan(x) + 1) / (tan(x) -1) = (sec(x) + csc(x)) / (sec(x) - csc(x))? If sec(x) = 7, what is sin(x)?
