What will be the value of cos A If sin a greater than 1?

So 0 is the answer.

Is it true that Sinx COSX 1?

Because sin(2x)≤1 for all x∈R (for all real-valued x ) that means that cos(x)sin(x)≤12 for all real x .

Where is Sinx greater than COSX?

Since 1>. 84, the max of cos(sin x) is greater than -sin (cos x) and since the two functions never intersect because sin x = cos x =1/root2 only when x=pi/4 then cos(sin x) > -sin (cos x) for all values of x.

What is the greatest value of Sinx Cos?

Hence the maximum value of sinx-cosx is $\sqrt{2}$.

Why can’t the sine of an angle 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.

How do you find Sinx COSX?

The equation sin x = cos x can also be solved by dividing through by cos x. If we put k = 0 and k = 1 we get the solutions /4 (45°) and /4 + = 5 /4 (45°+ 180°= 225°). To solve the inequality sin x > cos x we need to see which is the greater sin x or cos x on the intervals between the solutions /4 and 5 /4.

What is the maximum and minimum value of Sinx COSX?

a*sinx + b*cosx, maximum & minimum value is (+,-)√[a^2+b^2]. As here a=b=1, maximum and minimum value of sinx + cosx = (+,-)√[1^2+1^2], i.e. +√2 is maximum value and -√2 is the minimum value. Originally Answered: What is Maximum and minimum value of sin x +cos x?

What are the maximum and minimum values of sin(cosx)?

In order for sin to reach its maximum, it has to have a parameter of /2, which is greater than 1. Cos, however, can be 1 when sin x=0. As it turns out, sin (cos x) has its maximum where x=0. What about at the minimums? Well, the lowest value for cos sin x is cos 1, which is > 0. sin cos x, however, is negative when cos x < 0.

What is the range of sin and cos?

The range of sin and cos is [-1, 1]. In order for sin to reach its maximum, it has to have a parameter of /2, which is greater than 1. Cos, however, can be 1 when sin x=0.

What is the value of coscosx cosy?

cosx cosy= 2sin. x+y 2. sin. x y 2. The Law of Sines sinA a = sinB b = sinC c Suppose you are given two sides, a;band the angle Aopposite the side A. The height of the triangle is h= bsinA.
