(Sin theta -2sincube theta)=(2coscube theta -costheta)tan theta prove it |
| Answer» Taking RHS take cos (2cos2-1)tan But tan can be written as sin÷cos Cos(2cos2-1 ) ×sin ÷ cos Cos canclled with cos thus it is sin (2cos2-1) Now take LHS sin(1-2sin2theta)Sin (sin2+cos2-2sin2) ,1 = sin2+cos2 Sin (cos2-sin2)Sin (cos2 -1+ cos2)Sin (2cos2-1 ) Thus lhs = rhs hence proved | |

Answer» Badhiya? Mst Ksa h? ? Hi Suhu Thank u Thanx? Ok? The answer is √2 As sin² + cos2 = 1 √Sin² + cos² +sin² + cos² In first step there is mistake it was [sin+ cos)² Root(Cos²+sin²-2 × sin × cos + sin²) + (cos² + 2 × sin ×cos) √(cos-sin)²+(sin-cos)² ? Using that we can solve as followa To calculate on cartesin plane use the distance formula √2 ? On cartesian plane? |

Prove root 5 is irrational no. |
|
Answer» Its wrong yrr Let us assume that √5 is a rational number.we know that the rational numbers are in the form of p/q form where p,q are intezers.so, √5 = p/q p = √5qwe know that \'p\' is a rational number. so √5 q must be rational since it equals to pbut it doesnt occurs with √5 since its not an intezertherefore, p =/= √5qthis contradicts the fact that √5 is an irrational numberhence our assumption is wrong and √5 is an irrational number.\xa0 |
