Trigonometric identities are formulas that involve Trigonometric functions. Trigonometry is a branch of mathematics that deals with the study of relationships between lengths and angles of triangles. The early applications of the trigonometric functions were to surveying, navigation, and engineering. These functions also play an important role in the study …
How to find the range of asinx+bcosx+c ? Since and is defined for all real values of , so the domain of the given function is the set of all real numbers. We have to find the range of asinx+bcosx+c . For the time being, assume that …
Sequences and Series Tricks : Arithmetic and Geometric Sequences Both arithmetic and geometric sequences are important concept of sequences and series . Questions from AP & GP are asked in various competitions including SSC and Railways. Here, are some important formulas that you can use to solve questions based on …
Definite Integration Involving Modulus Function There is no anti-derivative for a modulus function; however we know it’s definition Thus we can split up our integral in two parts. One part must be completely negative and the another must be completely positive. This strategy is known as splitting . To split …
In this article , some important algebra questions asked in SSC CGL previous year papers are discussed with explanations. 1. If then find (i) (ii) (iii) (iv) Sol. Given . Squaring both sides we get, . Hence (i) Now = Putting , we get = =1 …
