+    Syntax:
+
+    ```
+    operation ::= ssa-id `=` `std.sin` ssa-use `:` type
+    ```
+
+    The `sin` operation computes the sine of a given value. It takes one
+    operand and returns one result of the same type. This type may be a float
+    scalar type, a vector whose element type is float, or a tensor of floats.
+    It has no standard attributes.
+
+    Example:
+
+    ```mlir
+    // Scalar sine value.
+    %a = sin %b : f64
+
+    // SIMD vector element-wise sine value.
+    %f = sin %g : vector<4xf32>
+
+    // Tensor element-wise sine value.
+    %x = sin %y : tensor<4x?xf8>
+    ```
+  }];
