If anybody could please help me on at least one of these or point me in the right direction it would be greatly appreciated. My teacher showed me how to do 95 and used the cofunction identity except her work didn't make sense. That's as far as I got. For exercises 95-100, verify the identities for a right ️ABC

95. sin2A=sin2B

96. cos2A=-cos2B

97. tan2A=(2ab)/(b^2-a^2)

98. cos2A=(b^2-a^2)/(c^2)

99. cos A/2 = sqrt(c+b)/sqrt(2c)

100. tanA/2 = (c-b)/a
