Scientific tab

Use the Scientific tab to calculate expressions using scientific operations.

When you select a function, the current expression is enclosed in brackets and the function is performed on the value of the current expression.

Use the following options:

• sin — Calculates the sine of the current expression.
• cos — Calculates the cosine of the current expression.
• tan — Calculates the tan of the current expression.
• asin — Calculates the angle whose sine is equal to value of the current expression.
• acos — Calculates the angle whose cosine is equal to value of the current expression.
• atan — Calculates the angle whose tangent is equal to value of the current expression.
• ^ — Raises the current expression to a specified power.

  For example, if the expression is 2 and you select ^, then enter the value3, the following calculation is performed:

  (2)^3=2*2*2=8

  ^2 — Calculates the expression to the power of 2.

  ^3 — Calculates the expression to the power of 3.

• exp — Calculates the exponential value of the current expression with respect to e, the base of the natural logarithms.

  For example, if the current value of the expression is 2 and you select exp, the following calculation is performed:

  exp(2) = e2 = 7.389056

• ln — Calculates the natural logarithm of the current expression.

  For example, if the current value of the expression is 7.389056 and you select ln, the following calculation is performed:

  ln(7.389056) = logarithm(7.389056) = 2

• abs — Calculates the absolute value of the current expression. In other words, removes the minus sign.

  For example, if the value of the expression is -56.98 and you select abs, the new value is 56.98.

• ( ) — Adds brackets around the current expression.
• ( — Adds a single left bracket to the current expression.
• ) — Adds a single right bracket to the current expression.
