This calculator app that focuses on creating calculator features need to do on the field of engineering I can manufacturing.
It is a simple calculator that can calculate trigonometric functions, even if I do not know.
Calculation can be right-angled triangle, scalene triangle.
Again, memory, memory answer, π, trigonometric functions, parentheses calculations, you can.
Deployment Deployment cone (including misalignment), obliquely cut pipe, cut R, tube T, shrimp tube, rounded corners, rounded corners (eccentricity), the eccentric hopper, expansion of the pipe from the end plate, the connecting pipe to the tapered tube deployment can be deployed, the wing screw, the calculation of the PCD.

Unit calculator
The numbers that are displayed on the label, tap the white button, you can enter.
By swiping the screen left and right, a right-angled triangle is rotated.
Right triangle is inverted by swiping up and down the screen.
Please enter a right triangle in three places in two places, the scalene triangle.
In Tap "Cal", the calculation result is displayed.
In the "Cl" button, the numerical value of the display is cleared.
You can also display the label in the "0" to turn off only the specified location.
Numerical calculation results, and slide down to the touch of a button, you can see the label, you can use the following to calculate.

Epitasis
The input method is the same as the calculator.
Pipe expansion, PCD, choose a mirror exploded view by sliding to the left or right of the screen.
Input is required to all buttons basically, you can be "0" in some locations.
By double-tap the screen after entering the values ​​of the rounded corners, rounded corners (eccentricity) is switched to the input screen.
Division of the circumference, please enter a multiple of 4.
Of the calculated figure, so images, in the form of a fact, it is different.
