a COS theta + b SIN theta - maximum and minimum values

WebAs sin² θ is preceded by a negative sign therefore we have to take maximum value of sin² θ in order to get minimum value. Converting into a cos equation: = 2sin² θ + 3cos² θ = 2 (1- cos² θ) + 3cos² θ = 2 – 2cos² θ + 3cos² θ = 2 + cos² θ = 2 + 0 = 2 (option ‘B’) 3. The maximum value of sin x + cos x is A) √2 B) 1/√2 C) 1 D) 2 Solution: Figure 3 shows the relative errors of the small angle approximations. The angles at which the relative error exceeds 1% are as follows: • cos θ ≈ 1 at about 0.1408 radians (8.07°) • tan θ ≈ θ at about 0.1730 radians (9.91°) grow infinite

[Solved] Find the maximum value of sinθ + cosθ. - Testbook

WebWe know that the minimum value of the cosine function −1 and this occurs when x − α = π, i.e. when x = π + α. So the minimum value of f(x) is 5×−1−3 = −8. So, very quickly and with the minimum amount of work we have established a maximum value and a minimum value, and based upon this information we could go ahead and sketch a graph WebA launch angle of 45 degrees displaces the projectile the farthest horizontally. This is due to the nature of right triangles. Additionally, from the equation for the range : We can see that the range will be maximum when the value of is the highest (i.e. when it is equal to 1). Clearly, has to be 90 degrees. Web( Because we know maximum and minimum values of Sin θ, Cos θ ? and by using simple identities we can convert all trigonometric functions into equation with Sine and Cosine.) = 1 + 2 + (1/ cos 2 θ) + (1/ sin 2 θ) solving taking L.C.M = 1 + 2 + (sin 2 θ + cos 2 θ)/ ( sin 2 θ . cos 2 θ)…..eq1 but we already know two things growinfinite
