Learn trigonometry with ease in a graphical and interactive way.<br><br>Simple usage instructions:<br>use one fingers to rotate the axis.<br><br>Trigonir© is a product of a long lasting career in education. Teachers of mathematics have long been searching for a way to present trigonometric functions to students in an easy to understand yet professional manner, since the expression sine alone tends to evoke a feeling of discomfort among quite a few students. <br><br>This learning aid is the result of this consideration and has already been tested in various schools in Europe. Trigonir© brings forth a new, creative and interesting approach to analyzing and using trigonometric functions, which renders them understandable to all students, including those, who are not very fond of mathematics. <br><br>Trigonir© is comprised of two planes that are connected and movable. The bottom plane has the unit circle, angles from 0° to 360°, the tangent and cotangent axis as well as the values of trigonometric functions for basic angles inscribed on it. Red color is used to emphasize the negative values of trigonometric functions. <br><br>The upper plane has only one axle inscribed on it and can be moved circularly in order to determine various attributes of trigonometric functions for various angles. <br><br>Trigonir© enables us to determine the following properties of trigonometric functions:<br> <br>- domain and co domain of functions, <br>- zeros of functions, <br>- points where a function is not defined, <br>- increasing and decreasing of the <br> function, <br>- positive/negative values, <br>- periodicity, <br>- evenness and oddness of a function, <br>- accurate value of basic angles, and <br>- properties of inverse functions (arcsin <br> α, arccos α , arctan α , arccot α). <br><br>The objectives of the learning aid Trigonir© are: <br><br>- less time spent on handling <br> trigonometric functions, <br>- a more interesting presentation of the <br> subject,<br>- a more active involvement of students <br> during lessons, and <br>- making studying easier and more <br> independent.
User reviews affect conversion to installs and app rating. Featured and helpful reviews are the first to be noticed by users and in case of no response can affect download rate. This is why it is highly recommended to reply to them.
Please, add a easier way to move around the circle... Pressing 50x for sen 50, for example, is terrible! Not particle at all. 5 stars if you fix this...
for the commenters: use two fingers to move the line to whichever degree you like. works perfectly for me and my students.
This app is useless to me. Only shows standard graph of sine and cosine. Not worth the dollar I paid, but now that I've tried it I wouldn't even take it for free.
