SecA = 1/CosA

Hence

SecASinA = SinA/CosA = 0

Then SinA = 0

A = 0 , 180, 360

It doesn't matter what the value of CosA is because if CosA = 0 , then the answer is undefined. 44e/.g/

SinA/CosA = SinA / 0 = Undefined.

What is the cos of angle 'a' with the measurements 5 13 12?

Use Cosine Rule a^(2) = b^(2) + c^(2) - 2bcCosA Algebrically rearrange CosA = [a^(2) - b^(2) - c^(2)] / -2bc Substitute CosA = [13^(2) - 12^(2) - 5^(2)# / -2(12)(5) CosA = [ 169 - 144 - 25] / -120 Cos)A) = [0] / -120 CosA = 0 A = 90 degrees (the right angle opposite the hypotenuse)/ However, If 'A' is the angle between '12' & '13' then 'a' is the side '5' Hence (Notice the rearrangement of the numerical values). CosA = [5^(2) - 12^(2) - 13^(2) ] / -2(12)(13) CosA = [ 25 - 144 -169] / -312 CosA = [ -288[/-312 CosA = 288/312 A = Cos^(-1) [288/312] A = 22.61986495.... degrees.


What is value of 0 deger in trigonometric?

The value is 0.


What is tan of 0?

Tan(0) = 0 Remember Tan(0) = Sin(0)/Cos(0) = 0/1 And Sin(0) = 0 Hence it follows that Tan(0) = 0


Why are there two sine cosine and tangent ratios?

There aren't. There are three: Sine, Cosine and Tangent, for any given right-angled triangle. They are related of course: for any given angle A, sinA/cosA = tanA; sinA + cosA =1. As you can prove for yourself, the first by a little algebraic manipulation of the basic ratios for a right-angled triangle, the second by looking up the values for any value such that 0 < A < 90. And those three little division sums are the basis for a huge field of mathematics extending far beyond simple triangles into such fields as harmonic analysis, vectors, electricity & electronics, etc.


If in a triangle tanA plus tanB plus tanC equals 0 then cotAcotBcotC equals?

cotA*cotB*cotC = 1/[tanA+tanB+tanC]
