Product Code : EL-MLE-9790
Jlab Export is a leading Hands-On Trigonometry Proof Manufacturer,and suppliers in India
Hands-On Trigonometry Proof (code EL-MLE-9790) is a set of pieces for four separate visual “proofs” of trigonometric relations, covering the Pythagorean identity, a sum formula, a double-angle formula and two sum-to-product formulas. Students rearrange the pieces to establish equalities of areas or lengths, guided by colour instructions and four reproducible worksheets. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Hands-On Trigonometry Proof Used For?
Trigonometric identities usually reach students as lines of algebra. This set turns them into shapes: when two arrangements of the same pieces cover equal areas, or line up into equal lengths, the identity they stand for becomes something students can see and check by hand. The Pythagorean identity, for example, comes from a right triangle with a hypotenuse of length one, whose other two sides are the sine and the cosine of an angle, so sine squared plus cosine squared equals one.
The demonstrations are visual, common-sense proofs, not rigorous ones; their job is to make abstract relationships real and believable, and handling the pieces engages students more than looking at a proof on paper. The Pythagorean identity is part of CBSE class 10 trigonometry, and sum, double-angle and sum-to-product formulas are taught in class 11, so the set suits senior-secondary maths lessons and the school maths lab.
What to Specify When Ordering

Frequently Asked Questions
Which trigonometric relations does the set cover?
Four separate proofs covering the Pythagorean identity, a sum formula, a double-angle formula and two sum-to-product formulas.
How is each proof demonstrated?
By physically rearranging the pieces to establish equalities of areas or lengths. Colour instructions describe each proof, and four reproducible worksheets reinforce the material.
Are these formal mathematical proofs?
No. They are visual, common-sense proofs that help make the relationships real and believable, rather than rigorous mathematical proofs.
What information is needed for an export quotation?
Send the number of sets, the destination country and port or city, the delivery terms you want (for example FOB or CIF), any packing or labelling instructions, and the tender reference if there is one.
Who manufactures the Hands-On Trigonometry Proof?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maths lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The proof set is made at JLab’s own works, not bought in from a trader, so schools, dealers and importers buy direct from the maker and repeat orders come from the same source. JLab exports worldwide and ships to buyers in every region — for example Qatar in the Middle East, the Czech Republic in Eastern Europe, Kyrgyzstan in Central Asia, Guyana in South America and Morocco in North Africa. Tender information is on the JLab lab tenders page.
