The least value of 8cosec 2x + 25 sin2 x is:
SpletThe least value that cos 2 θ can take is 0 So, the required least value = 3 + 0 = 3 ∴ The least value of 3sin2 θ + 4cos2 θ = 3 Important Points It must be remembered here that: Although cos θ can take any value from -1 to +1, but the value of cos 2 θ can never be negative. Hence, the minimum value of the cos 2 θ will be zero.
