If the value of `cos9^@ - sin9^@=sqrt2sinalpha`, where `a in [0, 3pi]`, then the value of `'alpha'` can be -

If cos9alpha=sinalpha and 9alpha lt 90^(@) , then the value of tan5alpha is

If cos9alpha=sinalpha and 9alpha lt 90^(@) , then the value of tan5alpha is

The value of : (cos9^@+sin9^@)/(cos9^@-sin9^@) is:

If cos9alpha=sinalpha and 9alpha<90^@ then the value of tan 5alpha is

The value of int_0^(pi/2) sin|2x-alpha|dx, where alpha in [0,pi], is (a) 1-cos alpha (b) 1+cos alpha (c) 1 (d) cos alpha

The value of int_0^(pi/2) sin|2x-alpha|dx, where alpha in [0,pi], is (a) 1-cos alpha (b) 1+cos alpha (c) 1 (d) cos alpha

The value of int_0^(pi/2) sin|2x-alpha|dx, where alpha in [0,pi], is (a) 1-cos alpha (b) 1+cos alpha (c) 1 (d) cos alpha

The value of sin^(-1)((cos(pi/9))

If in the interval [0,pi] the value of 5 sin^(2) alpha + 3 cos^(2) alpha be equal to 4, then what will be the value of sin 2alpha
