What is the maximum value of sinx COSX?

Maximum value of sin(2x) is at x = 45° because sin 90° = 1 (max). Therefore, maximum value of sin(x)cos(x) = (1/2)×1 = 1/2 or 0.5.

What are the greatest and least value of sinx COSX?

Maximum value is 1/2 and minimum value is -1/2.

What is the formula of sinx COSX?

Answer : The expression for sin x + cos x in terms of sine is sin x + sin (π / 2 – x).

What is the maximum value of sinx?

for y= sin(x). The maximum value is 1 and the minimum value is -1.

What is the minimum value of sin A?

The sine function ranges between -1 and 1, so the minimum is -1 and the maximum is 1.

What is the minimum value of 3cosx 4sinx 8?

Hence, the minimum value of 3cosx+4sinx+8 is 3.

How do you convert Sinx to COSX?

Cosine is an even function; hence, cos(x)=cos(−x). For cos(−x+π2), you can multiply the argument by −1 and not change the value of the function, which gives cos(x−π2). Now the transformation is clearly a shift to the right by π2 which yields the sine function.

What is the minimum value of sinx?

−1
The minimum value of sinx is −1. At x = 270°, sinx = −1.

What is minimum value of sinx?

How to find maximum and minimum values of sinxcosx?

How to find the value of sin2x/2?

Multiply by 2 in numerator and denominator . 2sinx cosx / 2 Sin2x /2 (using sin2A = 2sinAcosA) (Value of sin lies between -1 to +1) -1<_ sin2x <_ +1 Divide by 2 -1/2 <_ sin2x/2 <_ +1/2 Therefore minimum value = -1/2 Maximum value =+1/2 Still looking for help?

What is the maximum and minimum value of mod sin x?

The minimum value of mod sin x (or mod cos x) is zero. But corresponding to this the other will have a maximum value which is one. But if you will go further one of them will decrease while other will increase. Hence the value will surely exceed one. The Rock reveals the key to success for normal people.

How to find maxima and minima of sin x + b cos x?

There is a simple formula for maximum and minimum value of the expression of form a sin x +b cos x. This method follows the concept for maxima and minima. so to find maxima we will first differentiate the above expression and then equate it to 0.
