What is the trigonometry ratios table? It is a type of table by this table we can find out the value of some specific angles like 0º,30º,45°,60°and 90º. So it is essential that you know how to make this table, here I am going to explain this table in a very easy manner here I…
Q 1. In ΔABC, right-angled at B, AB = 24cm, BC = 7cm. Determine: (i) sin A, cos A (ii) sin C, cos C Given: In ΔABC ∠B = 90° AB = 24 BC = 7 To Find: (i) sin A =? Cos A =? (ii) sin C =? Cos C =? Solution: By PGT…
Trigonometric identities are very important during solving Questions. Here are the following identities which are used to solve or prove the questions. I. sin2 θ + sin2 θ = 1 (a) sin2θ = 1 – cos2 θ (b) cos2θ = 1 – sin2θ II. 1 + tan2θ = sec2θ (a) tan2θ = sec2θ – 1…
We have already studied the triangle and also the types of a triangle in Previous classes. Here we will discuss a particular type of triangle i.e. right-angled triangle. Let us take some examples where we use a right-angled triangle: If you go to Delhi to visit the Qutub Minar so you can find out the…
In mathematics indices or index is the value that is raised to the power of any variable or constant like x raised to power 2 i.e. x2. Where x is a variable and 2 is called the power or exponent of that variable. Let’s see an example: axm Here a = coefficient x = base…
Mathematics वन ऑफ द मोस्ट पॉपुलर सब्जेक्ट्स में से एक है। और अगर आपको एक अच्छा टीचर और प्रॉपर गाइडेंस मिल जाये तो आप इसे एक सब्जेक्ट की तरह नहीं, एन्जॉय करते हुए पढ़ेंगे। जैसा की हम जानते है की, हमने मैथमेटिक्स के चलते इम्पॉसिबल चीजों को हल लिया है। जैसे की चाँद तक पहुँचना,…
