sin（-510°）等于．

Question

sin（-510°）等于______．

sin（-510°）等于______． sin（-510°）等于______． sin（-510°）等于______． sin（-510°）等于______．

Answer 1

sin（-510°）=sin（-510°+360°）=sin（-150°）=-sin150°=- (1)/(2)
故答案为- (1)/(2)

sin（-510°）=sin（-510°+360°）=sin（-150°）=-sin150°=- (1)/(2)
故答案为- (1)/(2) sin（-510°）=sin（-510°+360°）=sin（-150°）=-sin150°=- (1)/(2)
故答案为- (1)/(2) sin（-510°）=sin（-510°+360°）=sin（-150°）=-sin150°=- (1)/(2)
故答案为- (1)/(2) sin（-510°）=sin（-510°+360°）=sin（-150°）=-sin150°=- (1)/(2)
故答案为- (1)/(2) (1)/(2) 1 2 1 1 1 2 2 2
故答案为- (1)/(2) (1)/(2) 1 2 1 1 1 2 2 2
