If 4 tanQ=3 then find the value of 4sinQ-cosQ/4sinQ+cosQ |
|
Answer» 4tanθ = 3 so, tanθ = 3/4 Now, (4sinθ - cosθ)/(4sinθ + cosθ) First of all DIVIDE cosθ with both LHS and RHS , (4sinθ/cosθ - cosθ/cosθ)/(4sinθ/cosθ + cosθ/cosθ) = (4tanθ - 1)/(4tanθ + 1) Now, put tanθ = 3/4 = (4 × 3/4 - 1)/(4 × 3/4 + 1) = (3 - 1)/(3 + 1) = 2/4 = 1/2 HOPE IT HELPS YOU!!

SinA+ cos A=√2sinA then,sinA-cosA= |
Answer» Given :To find :
Solution :Sin A + Cos A = √2 sin A
(sin A + cos A)² = (√2 sin A)²
Sin² A + Cos² A + 2SIN A Cos A = 2 sin²A ____(1) Using Identity Sin² A + cos ² A = 1 Sin² A = 1 - cos² A ______(2) Using equation 2 JININ n equation 1 : 1 - cos² A + cos² A + 2 sin A cos A = 2 ( 1 - cos²A) 1 + 2 sin A cos A = 2 - 2 cos² A 2 sin A cos A = 2 - 1 - 2 cos² A 2 sin A cos A = 1 - 2cos² A 2cos² A = 1 - 2 sin A cos A 2Cos² A = sin² A + cos² A - 2 sin A cos A Now , Using identity ( x - y)² = x² + y² - 2xy 2Cos² A = ( sin A - cos A)² Sin A - cos A = √(2 cos² A) Sin A - cos A = ± √2 cos A |
