conditional trigonometric equations

In the above topics many identities have been discussed. They are true for all values of the angles for which trigonometric functions are defined. In this section we prove identities, where a certain relationship exists among the angles considered. Many interesting and importa..

A conditional sentence is about the connection between two things, two events etc. It expresses the idea that one thing follows from another, or depends on another: The meaning of a conditional sentence depends on the tenses of the verbs within ..

There are some conditions associated with the process of combustion. The substance to be burnt must be combustible (the substance must catch fire easily). Wood, paper, coal, coke, hydrogen, liquified petroleum gas, natural gas, petrol, kerosene, diesel, alcohol, ether etc. are some of the..

Temerature Pressure Catalyst Promotor 450-500 C 152000-684000 mm of Hg Iron Molybdenum The reaction in Habers process is exothermic and so external heating is not required once the reaction starts. Lowering the temperature to 450 o - 500 o C favours the reaction, bu..

A trigonometric equation is an equation involving the trigonometric functions of unknown angles. Example; sin x = 1/..

The trigonometric ratio's are: Sine, Cosine, Tangent, Cotangent, Secant, and Cosecan..

Introduction - The t-ratios of acute angles are given in tables of natural sines, natural cosines and natural tangents. In this chapter, we will discuss (i) how to read trigonometric tables, (ii) how to find the angle when the value of a t-ratio is give..

The circle whose radius is 1 unit whose centre is the origin of a rectangular co-ordinate system is called the unit circle. 1. cos q = x. 2. sin q = y. 3. tan q = y/x. 4. sec q = 1/x. 5. cosec q = 1/y. 6. cot q = x/y. The six functions of q defined by the above equation are..

Some Trigonometrical Identities - 1. sin A = cos (90 o - A) 2. 3. tan A x tan (90 o - A) = 1 4. sin 2 A + cos 2 A = 1 5. 1 + tan 2 A = sec 2 A 6. 1 + cot 2 A = cosec 2 A Let us prove the above identities. Let D ABC be a right-angled triangle with B = 90 o . Let BC = a, AC = b and AB = c. ..
