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.
