What is COSX COSY?
What is COSX COSY?
cosx + cosy = 2 cos(x+y. 2. )cos(x−y.
Is COSX COSY Cos X Y?
6 Answers. which’s obviously false. The maximum value of cos(x+y)=1. The maximum values of cos(x) and cos(y) are 1.
What is the value of COSX?
The maximum value of cosx is 1. At x = 0° and x = 360°, cosx = 1. The minimum value of cosx is −1.
What is the value of Sinx COSX?
Hence the maximum value of sinx-cosx is √2.
What is the maximum value of COSX?
∴The maximum value of cos(cosx) is cos0∘=1. The minimum value of cos(cosx)is cos1. Note: Cosine is a decreasing function. It has maximum value 1 when x=0∘ and minimum value 0 when x=π2.
What is value of sec theta?
the equation sec(theta)=-1 turns to 1/cos(theta)=-1, which is equivalent to cos(theta)=-1. The only values of theta that satisfy this are theta=pi +2k pi for k in ZZ. If you prefer the notation with degrees: theta=180°+360°k for k in ZZ.
How do you find the maximum and minimum value of trigonometric identities?
Ratta-fication formulas
- a sin θ ± b cos θ = ±√ (a2 + b2 ) { for min. use – , for max. use + }
- a sin θ ± b sin θ = ±√ (a2 + b2 ) { for min. use – , for max. use + }
- a cos θ ± b cos θ = ±√ (a2 + b2 ) { for min. use – , for max. use + }
- Min. value of (sin θ cos θ)n = (½)n
What is the value of sin 1 1?
The inverse sin of 1, i.e., sin-1 (1) is a very unique value for the inverse sine function. Sin-1(x) will give us the angle whose sine is x. Hence, sin-1 (1) is equal to the angle whose sine is 1. Since the inverse sin-1 (1) is 90° or Π/2.
What is the largest number the sine of an angle could be?
A = 1 is if a = c, but that would make for a strange triangle!), the sine ratio cannot be greater than 1.
Why can sin never be greater than 1?
Note: Since the sine and cosine ratios involve dividing a leg (one of the shorter two sides) by the hypotenuse, the values will never be more than 1, because (some number) / (a bigger number) from a right triangle is always going to be smaller than 1.
Can a sine of an angle equal 2?
Sine of an angle cannot be 2,as you must be knowing, sin90=1,u may conclude that sin180=2. but 180 degree cannot be an angle of a triangle, Hope this helps!
