( (0.34202014+(cos)(x))⋅ (sec)(x)=0/((cos)(x)))Rewrite ( (sec)(x)) in terms of sines and cosines.( (0.34202014+(cos)(x))⋅ 1/((cos)(x))=0/((cos)(x)))Simplify terms.( (0.34202014)/((cos)(x))+1=0/((cos)(x)))Simplify each term.( 0.34202014(sec)(x)+1=...
You enter the argument x, and the value of cos-1(x) appears in the blink of an eye. But please remember that you must not enter values that are not between -1 and 1! Have you noticed our tool *converts between radians and degrees?. No need to search for any additional tools!

( (sin)(x/2)=√((1-(cos)(x))/2)) 相关知识点: 试题来源: 解析 Since the radical is on the right side of the equation, switch the sides so it is on the left side of the equation.(√((1-(cos)(x))/2)=(sin)(x/2))To remove the radical on the left side of t...
Take the inversecosine of both sides of the equation to extract ( x) from inside the cosine.( 2x+3=(arccos)(1/2))The exact value of ( (arccos)(1/2)) is ( (π )/3).( 2x+3=(π )/3)Subtract ( 3) from both sides of the equation.( 2x=(π )/3-3)Divide each term by ...
