Reduce the index of the radical and exponent with 2
Reduce the index of the radical and exponent with 2
Since 1−2sin(45)<0,the absolute value of 1−2sin(45) is −1+2sin(45)
Since 1−2cos(45)<0,the absolute value of 1−2cos(45) is −1+2cos(45)
Subtract the terms
More Steps
Simplify
−1+2sin(45)−(−1+2cos(45))
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−1+2sin(45)+1−2cos(45)
Since two opposites add up to 0,remove them form the expression
2sin(45)−2cos(45)
Multiply the terms
