Why is there a demand for Class 10 Maths Olympiad Online Tuition?
The chapter trigonometry, which is a fear of many students, dates back to the ancient Egyptians. It mainly deals with the triangle's side, angles, and functions. The right triangle is the most frequent in trigonometry and forms the base for the Pythagorean Theorem, which asserts that the squares of both sides of a right triangle equal the square of its longest side or hypotenuse. Pythagorean triples are sided lengths that result in whole integers when used with the equation (a2 + b2 = c2). Although, there are several trigonometric ratios such as sine, cosine, tangent, and inverse functions secant, cosecant, and cotangent. The ratios of the triangle's sides are used to find these functions. You might have heard several ways to remember the trigonometry formula; the following is one of the simplest and easiest tricks to learn the formula.

Using this, let us apply this in the trigonometry formula
sin= P/H or, Perpendicular/ Hypotenuse
cos= B/H or, Base/ Hypotenuse
tan= P/B or, Pendicular/ Base.
Similarly, the vice versa of sin, cos, and tan is the formula of secant, cosecant, and cotangent. This chapter carries a great advantage in the Maths subject; if you check the question paper of the class 10 Maths Olympiad Examination, then maximum questions are asked from this chapter. Let us see a few sample questions asked in class 10 Maths Olympiad exam.
Sample Questions:
In a trapezium named ABCD, AB and DC are parallel, and BC is perpendicular. If angle DAB = 45 degree, CD = 3 cm, BC is 2cm then find AB.
5 cm
3 cm
4 cm
2 cm
234m is the perimeter of the right-angled triangle, and the hypotenuse measures 97 m. Therefore find out the measurement of the other two sides of the triangle.
80 m and 57m
100 m and 37 m
72 m and 65 m
None of the above
