Given: 2sin-1x = cos-1x
Since comma space sin to the power of negative 1 end exponent straight x plus cos to the power of negative 1 end exponent straight x equals straight pi over 2 rightwards double arrow 2 open parentheses straight pi over 2 minus cos to the power of negative 1 end exponent straight x close parentheses equals cos to the power of negative 1 end exponent straight x rightwards double arrow straight pi minus 2 cos to the power of negative 1 end exponent straight x equals cos to the power of negative 1 end exponent straight x rightwards double arrow straight pi equals 3 cos to the power of negative 1 end exponent straight x rightwards double arrow straight x equals cos straight pi over 3 rightwards double arrow straight x equals 1 half
