Find maximum value of \(\frac\) Question 3. If sin θ = cos θ, then find the value of 2 tan θ + cos 2 θ. Solution: sin θ = cos θ (Given) It means value of θ = 45° Now, 2 tan θ + cos 2 θ = 2 tan 45° + cos 2 45° Question 4. If sin (x – 20)° = cos (3x – 10)°, then find the value of x. Solution: sin (x – 20)° = cos (3x – 10)° ⇒ cos [90° – (x – 20)°] = cos (3x – 10)° By comparing the coefficient 90° – x° + 20° = 3x° – 10° = 110° + 10° = 3x° + x° 120° = 4x° ⇒ \(\frac Filed Under: Primary Sidebar
